Shocking! This story is about two weeks late 🙂 I guess it’s hard to play nice when you all want the same thing: power!
This is pretty funny:

But Mr. McCain’s advisers, whose distaste for Mr. Romney is vivid, say Mr. McCain has been irked by what they perceive as misleading attacks and Mr. Romney’s willingness to say anything to be elected.
“He doesn’t play by the same rules the rest of us do,” said Charlie Black, a senior McCain strategist.

I agree that Romney says anything to get elected but so does McCain and Huckabee. Both have flip-flopped on illegal immigration and taxes. Romney is actually playing by McCain and Huckabee’s rules.
