For once, I'm ambivalent. On the one hand, I believe that John McCain's seriousness in approaching the war on terror makes it very, very important that he win. And so if he occasionally indulges in a little cringe-inducing criticism of the GOP, well, it's in a worthy cause.
On the other hand, there's the possibility that -- should he win having employed such strategies -- John McCain will interpret his victory as a mandate to continue criticizing his own party with more gusto than he does the Democrats'. And as I pointed out in a Townhall column predating McCain's clinching of the GOP nomination, such eager "bipartisanship" poses real dangers to conservatism in America.
