No idea at this point. Perry seems to be in the driver's seat, but he could always implode.
Perry and it will teach the party a lesson when the "true conservative" loses to Obama in an election that should have been won. Then in 2016 the GOP will nominate a much more respectable type like Chris Christie.
I wouldn't say that. I would expect the 2012 and 2016 candidates to not differ too extremely in terms of political beliefs, but the 2016 crowd seems at first glance more reasonable and likable than these jokers, so an illusion of moderation will be created.
