Tim Pawlenty

Former Minnesota Governor Tim Pawlenty announced this week the formation of a presidential exploratory committee - the first official step toward a 2012 presidential campaign. Pawlenty has credibility as both a fiscal conservative and as a social conservative, and he passed tax cuts and balanced the budget as Minnesota governor. But some wonder if Pawlenty has the charisma - or the competitive drive - to take home the GOP nomination. In the following slides, CBS News presents scenes from Pawlenty's political career over the past decade.
