All the speculation during the RNC was that Romney was sucking up to McCain knowing that 2012 he would get a chance to run again for the top spot no matter who won this election because McCain would not seek a 2nd term. AFAIK, McCain has never come out and said this, but he would be 80 years old at the end of his 2nd term.

Before anyone can compare Obama and Palin, the GOP has to take the leash off her. So far all she's capable of doing is give a speech with McCain looking over her shoulder.
