Mitch Daniels can win, he won in Indiana in 2008 with 57.8% of the vote. At the same time Republicans were being blamed for everything and Obama won Indiana in the presidential election. He's competent and not gaffe prone. Is he the most exciting? No, but Hillary isn't the most charismatic either. He knows how to campaign, govern, and not say something stupid. He's conservative enough for the base, and moderate enough for a general election. His time was obviously 2012, and he's not likely to run, but he'd be by far one of the best Presidential candidates.
Daniels/Paul 2016
Tim Pawlenty's ability to get elected in Minnesota is far more impressive. Dullards are dullards. Nobody would pay attention to anything Daniels has to say.
