Given Santorums’s history as a lobbyist, who are you supporting?
The man who would have been the obvious choice to have the GOP nomination in 2012 was Mark Sanford, former governor of South Carolina. His affair ended his chances at higher office (although somehow Newt Gingrich's multiple affairs haven't ended his chances). Mark Sanford would have given us executive experience, business experience, legislative experience and would have avoided the Mormon religion issues that are the real reason that many people hate Mitt Romney. If he had not had that affair, I might have supported him from the beginning. Either way, he'd be close to 700 delegates now and we wouldn't be having this argument.
A weaker choice would have been George Allen of Virginia. His background isn't as strong as some others, but he has executive experience as governor of Virginia. If he hadn't used a racial slur against a member of Jim Webb's staff, maybe he could have pulled out the win in 2006. In that case, he might have been a viable candidate this year.
