The Perils of Being a Front Runner

John McCain was a straight-talking upstart in the 2000 presidential election. Now he's poised to be the G.O.P. favorite for 2008, but at what cost?

As a rallying cry. "Common sense conservatism" doesn't have quite the ring of "Straight Talk Express." But the new slogan on the website of John McCain's presidential exploratory committee--a slogan he manages to repeat at least three times in every speech he gives these days--tells you all you need to know about how different this presidential campaign will be from his last one. McCain '08 will be a bigger, more conventional operation--a tank, not a slingshot. The prevailing wisdom about McCain used to be that his bipartisan appeal would make him a sure bet in a presidential race--if only he could get past the Republican primary. But as more and more of the party establishment climb aboard a campaign that McCain has not yet even formally launched, it's starting to look as if the opposite may be true. By trying to become the perfect candidate for the primaries, McCain could be creating difficulties for himself in a general election.
