There's a lot of conjecture and speculation on who the presidential candidates will choose as their running mates. On the Republican side, I think it will probably be Mitt Romney. While McCain had a hard fought primary battle in which McCain felt some of Romney's attacks were unfair, the general election is always another thing. In politics, a fierce rival can quickly become your political ally in short order. Witness Ronald Reagan and George Bush in 1980.
Why Romney? Initially, I didn't think it would be Romney. I thought it might be Governor Pawlenty, but now I've changed my mind. There are a few things Romney brings to the ticket that other people don't. He's tested, widely known commodity, mega fundraiser, could help win a critical state like Michigan and would be acceptable to most conservatives. On the first four Pawlenty doesn't have that advantage.
If McCain selects Romney and wins, I think Pawlenty would probably be offered a cabinet position. Personally, I hope Pawlenty remains in Minnesota rather than serve as VP or a cabinet member.
