I don't think McCain has any choice but to go with a younger, vibrant candidate for Veep. Crist or Romney fit the bill. That said, McCain desperately needs to throw a bone to the conservatives and he could go the route of Tancredo for Veep with the specific task of border control and immigration policy reform.
But if the economy is going to be the defining issue in the general election, he could choose Romney and have him tackle the economy.
He has a lot of good choices, but whatever it is he chooses, it better freaking “WOW” this conservative.
I think it would be extremely unwise for McCain to pick Crist. That would leave a very bad taste in the mouths of all of Romney’s supporters, myself included.
I am fully willing to accept McCain as the nominee with open arms, but putting Crist on the ticket would be adding insult to injury.
Romney is the obvious choice.
The only question is if McCain wants to win bad enough to make it.
