McCain looks like he is going to be the republican nominee although it is not 100%. Huckabee is still in the race even though it will take a lot for him to pull ahead. So the question is, will Huckabee be the VP choice? He would give McCain support from the more conservative side of the party that is having a hard time with McCain and would give Huck a platform for a future run, especially if McCain won. And with McCain's age, a second term would not be a forgone conclusion. I think Romney wants the job too, and some think he would be a better choice. I don't know, but its fun to watch. At least for this political junkie.
