Word was that Tim Pawlenty pulled out of the Republican presidential contest because he finished a weak third in Iowa's Ames Straw Poll two weeks ago. That's true, Republican sources tell the Huffington Post, but Pawlenty's campaign was also broke from spending heavily on Ames in hope of a better showing. How much did he owe? One source says $500,000, though others call that figure greatly inflated. The final accounting will become public when Pawlenty makes an FEC filing on Oct. 15. (More Tim Pawlenty 2012 stories.)
