Karl Rove joins the McCain campaign

Guess who is joining the McCain campaign?

Karl Rove, the president’s top political hand since his Texas days, recently gave money to McCain and soon after had a private conversation with the senator. A top McCain adviser said both Mehlman and Rove are now informally advising the campaign. Rove refused to detail his conversation with McCain.

I think we all know what this means. Any day now, you can expect to hear rumors that Barack Obama "has fathered a black baby."

On a serious note, this should once-and-for-all (though it won't) give lie to the idea of John McCain as a man of unwavering principle. You don't start consulting with Karl Rove just because you want to win; you consult him because you're willing to play dirty to win.
