Earlier today John McCain said that former NYPD commissioner Bernard Kerik's indictment calls into question Rudy Giuliani's judgment. The Giuliani campaign has responded, in force, issuing a document noting that John McCain had complimentary things to say about Giuliani even while Kerik's legal problems were in the news. The Giuliani campaign also raises the same issue as the McCain campaign finance irony watch. In the past, McCain and Giuliani have had only good things to say about each other. What happened? Finally: A question to which I'm pretty sure about the answer! Here it is: McCain is gaining ground nationally and in New Hampshire. In my opinion, Giuliani needs to win New Hampshire if he is to have a serious shot at the nomination. A resurgent McCain is the greatest threat to Giuliani's New Hampshire triumph. This is about to get interesting.
