All this talk about Bush and his daddy is hogwash. The man he really wants to outdo is John McCain. How else do you explain Bush’s belated admission that global warming is real, following so closely a big speech by McCain on the same subject?

McCain won kudos for breaking with Bush and his own party way back on Monday. But it seems that Bush doesn’t want McCain to top him in the history books any more now than he did during the South Carolina primary in 2000. The pair have walked hand in hand on Iraq, with McCain lending an air of authority to Bush’s decisions. Maybe Bush is a little hurt that McCain is seen as abandoning him on global warming.

Why would Bush be more obsessed with McCain than with his own dad? Consider first that the elder Bush probably wasn’t around much during the younger’s childhood. It would have been natural for W. to look outside for a father-figure. McCain probably isn’t the first to fill that role.

Much has been made of Bush the son following in his dad’s Air Force footsteps. But McCain also was a pilot — who made a name for himself in the very war Bush avoided.

Maybe it’s all just psychobabble, but I can’t help scratching my head about these two Republican leaders both acknowledging the reality of global warming in the same week. It has to be more than coincidence. I can understand why McCain did it — he’s been a consistent supporter of climate-change legislation. Bush has had seven years to think about it. Why now?

For all you Lego fans

I tend to harp on the perils and pitfalls of free-market medicine. But there’s one area where it seems to work, at least in my own life. So I figured I should give dentistry some due.

Last November, my dentist told me I needed $300 worth of work based, essentially, on readings given by a laser beam that a dental assistant shined through my teeth. This red beam allegedly showed the existence of unseen cavities caused by pinhole cracks. I balked. After all, my teeth felt fine (my gum line is another story). But the dentist insisted on the additional work. I told him I would get a second opinion. He graciously allowed that such a move was “my prerogative.” Thanks.

So this month, I went to a second dentist who doesn’t use the laser-pointer and said my teeth looked fine. He even said he would refrain from drilling unless really necessary. After all, dental procedures don’t always turn out as planned. And he told me what I could do on my own to arrest — and even reverse — any problems that might be stirring behind the enamel. The old dentist did no such thing.

As you can imagine, I now have a new dentist. He costs more per visit, $78 versus $55. But there are several key differences that make the extra cash worthwhile, even if it comes from my own pocket — which it does.

My new dentist does the cleaning himself rather than assigning it to an assistant. Second, he doesn’t push expensive procedures. The old dentist had TVs in the treatment rooms showing crooked and yellowed teeth turning white, shiny and straight, kind of like those ads showing Democratic candidates morphing into Osama bin Laden. I’m willing to pay more if I don’t have to resist that kind of marketing pressure every six months.

Dental care is unique in that regular care is relatively affordable and necessary, at least on a middle-class income. It also feels good to have a nice clean mouth for a day or two. And the more expensive-but-routine procedures are relatively limited. For the most part, it’s easy to compare.

Nonetheless, it was a fairly wrenching decision to change dentists. It wasn’t easy to disagree with a medical professional. They have a certain authority that’s hard to reject. I happen to be stubborn enough and didn’t have a long history with my first dentist. It would be tougher to reject a dentist or doctor I’d been seeing since childhood.

Some dentists certainly push what could be unnecessary care, and that could happen in the wider medical market. Maybe we could learn something from dentists, though. Where the sales tactics are too heavy-handed, it could encourage more people to get second opinions. It’s nice to see that where choice is available and exercised, there’s often a better one.

This is exactly the sort of thing suburban visitors need to see when they step out of their car in a downtown area struggling to return to life:

This particular ad — spotted May 10 — came from downtown York, catty-corner from the Central Market. I had to laugh. Fear of crime, justified or not, seems to be one of the biggest obstacles to bringing people into the city. What better way to erase people’s fears than to remind them that people they see on the street could be carrying both guns AND drugs?

I love going into the city, but I don’t like explaining pictures of three-foot tall guns to my children.

On another note, I think York County commissioner and anti-crime crusader Steve Chronister could take a few notes from this article about fighting urban violence. It might work better than ads.

If polls show that Barack Obama has trouble winning over working-class, less-educated whites, that’s science. But if Hillary Clinton mentions it, that’s playing the race card.

I managed to convince myself at one point that the dragging Democratic primary wouldn’t be harmful. Now I’m not so sure, but don’t blame Clinton. As was pointed out last weekend, the Democratic party is an odd mishmash. Republicans are, too, I suppose. That’s what happens when you try to cram tens of millions of political views into two opposing camps.

The continuing battle seems worse for Obama, in that it diminishes his ability to attract swing voters if he’s defined as the candidate of young people, African Americans and the college-educated (who, contrary to their own self-image, are a minority).

Sure, Obama is popular online, the Web somehow predicted his victory and he has won more votes in the Democratic primaries. But anyone who thinks the Democratic primary process — or the Internet — is the best way to pick a general-election winner should think again. The Internet may simply be replicating the losing touch of the primary electorate itself.

At any rate, it’s no accident that the only Democrat to win a presidential election since 1968 is Bill Clinton, and he was anything but a front-runner in the beginning. He lost Iowa in ‘92, if anyone cares to remember. And he probably wouldn’t have been too popular among the netroots, what with all his compromises, political and otherwise. OK, Gore won in 2000 — but he was vice president to a popular two-term candidate who couldn’t run again and probably would have been disowned by the party even if he had been able. (A friendly reader reminded me I left out Jimmy Carter, but pointed out that he was a long shot, too.)

The chief talking point against McCain is that he represents a third Bush term. Given Bush’s poor standing, that line of attack makes sense. But I don’t see it sticking. It just doesn’t ring true, certainly not as true as Obama’s supposed elitism. That bowling score (37, but in seven frames. So be fair: he could have rolled a 127 if every other ball were a strike) — and this picture — is going to come back to haunt him. Couldn’t he at least have unbuttoned his collar and loosened the tie? He must have been pretty uncomfortable with all that fabric tugging at his neck.

Plus, the far right will be contradicting the Dem’s attack on McCain’s behalf. Could it be the ultimate sucker punch? Conservatives hound McCain from the right knowing it will help him with independents and thereby paving his way to the White House? But let’s face it. Bush and McCain are very different men, have lived very different lives and have occasionally disagreed. Bush also won TWO TERMS. Let me go out on a limb and suggest that the polls showing low approval ratings have less to do with Bush and more to do with the way we expect people to perceive him, and the answers people believe they should be giving to the pollsters.

It’s also a tidy way to sweep him off the stage so the cameras can focus on the sequel rather than the pressing issues facing this country. Who wouldn’t want to watch a beauty contest — however ugly it gets — rather than a food shortage or a housing crisis?

I discovered a new site that let me create my own polls and offer YOU the chance to take them. This survey here allows you to take your pick in the 33rd Senate District race between Rich Alloway and Bruce Tushingham. Take a look and let me know what you think.

The outcome of this particular race isn’t much in doubt, so I’ll try to create additional polls that might actually offer some suspense.

The debate over the gas-tax holiday has gone far enough. It’s mostly a showpiece with little real-world effect (what would politics be without that sort of thing anyway?) Still, I’m willing to go along with it if we can come up with a more creative solution: force people to stop driving their SUVs and monster pickup trucks unless they’re hauling three passengers and/or a load of stuff.

Every time I venture out in my little Honda Civic, I’m surrounded by solo drivers in huge machines. It’s time for a little trade-off. I’m happy to spare those drivers some pain at the pump, but only if they’re willing to stop being the biggest, self-inflicting cause of it.

A friend of mine in a state that voted before PA warned me that I’d be burned out on the presidential race after the primary. He was right. It’s not worth following right now. It’s all about the horse race and the strategery, and I guess it will be for the next six months. Barack Obama has failed, in some respects, to move the media conversation off its sinking foundation in poll numbers, public gaffes and explosive preachers. Oh well.

I can’t complain too much, since I engaged in a little horse-racery myself. But we seem to have suffused the entire presidential process in a cynical brew. When John McCain denounces a negative ad, he’s seen as employing a backhanded trick to keep the ad in the news while keeping his own distance from it.

It’s probably ever been thus. Politicians are human and humans aren’t exactly the noblest of breeds, though we fight pretty hard sometimes to do good things. However, the crises do seem to be piling up pretty thick at the moment, from high fuel prices to food shortages to global warming to an unfinished war to nuclear terrorism (this site graciously lets you imagine the consequences of a bomb in your own hometown!).

Maybe it would be too much to ask people to pay significant attention to the bad stuff. Still, it’s no accident that the stories dominating headlines before 9/11 were about shark attacks and Gary Condit. We want to hear about a disaster only as long as it’s happening to other people, not to ourselves. The major media, safe in their NY/DC bubbles, are as insulated as our politicians, but not any more prone to seeking insulation than the rest of us.

I doubt that people whose homes have been hit by a tornado turn on the TV news to watch the aftermath — at least for now.

We have a winner in the 33rd Senate district’s write-in campaign on the Democratic side: It’s Bruce Tushingham, a retired teacher from New Oxford. According to the Chambersburg Public Opinion and other sources, Tushingham collected more than 1.600 votes. Rich Alloway, who won the Republican primary, came in second with 1,200 votes. Bob Curley, Jim Taylor and Cathy Cresswell, the three other candidates in the GOP primary, each took about 600 votes.

Alloway and Tushingham will have some company in Green Party candidate Andy Johnson. I hesitate to make a prediction in this race, but something tells me Alloway has a pretty good shot.

Give John McCain credit for a healthcare plan that goes beyond the traditional conservative mantra of “tort reform.” It’s actually a decent plan if you agree a free market is a good prescription for our healthcare woes. I for one would love a tax credit for buying my own health insurance, which I have to do because I’m self-employed. Too bad the market fails in reality.

It’s fun to dream of consumer power over healthcare decisions. But it’s ultimately a fantasy. I know this firsthand. My second son — who’s looked perfectly healthy on the outside during his 11 months so far — has a suspicious heartbeat that requires occasional and expensive tests to make sure it’s still not a problem.

We have a health-savings account, so we pay most of this stuff out-of-pocket. We could decide to forgo these tests, considering there appears to be little wrong with our son and he’s otherwise perfectly healthy. But, the doctors tell us there’s an outside chance of something bad cropping up. Do we really have a choice in spending the money? I guess. I do often suspect the doctors are being overly cautious and the tests may not really be necessary.

I could get a second opinion — for another couple hundred dollars. Or I could decide I’d rather spend all the money on iTunes and Amazon. What if I spurned the tests simply because I didn’t have the extra couple hundred dollars to spare? What’s good for the bank account may not always be good for the heart.

I know money should play a role somewhere in the healthcare equation, and something has to happen to rein in spending. But I can’t imagine complicating already-excruciating decisions for parents by forcing them to weigh family finances against a child’s health. Maybe the advocates of free-market healthcare think that’s a good thing, and they may even have a rational argument to support it. But the argument needs to be at or near the center of debate.

That’s the unspoken straight talk about consumer-driven healthcare.
