Roemer, who’s been the president and CEO of a bank during the two decades since his last run for Louisiana governor, said he’s been slowly adjusting back to life on the trail.He said he was "not comfortable" with some parts of politics and "re-learning" how to handle the press."I’m not as good as I thought I was," he said. "I think that’s very healthy to discover that. You tend after 20 years of absence to kind of glorify your skill at political debate."Still, Roemer said he’s sure that he compares favorably to his Republican rivals, whom he called "a field without distinction."But he did have kind words for Tim Pawlenty, who quit the race on Sunday after coming in third at Ames.Pawlenty is a "governor with a good track record," Roemer explained, but "he didn’t have the fire in delivery, and I think it hurt him."Roemer got to know Pawlenty when they roomed together at John McCain’s ranch during planning sessions for the 2008 campaign.Roemer’s positioned his campaign as an attack on the influence of special interest money and had harsh words for any candidate who uses PAC money - including Rick Perry, whom he likes, but who has several Super PACs."His weakness to me is raising funds at any cost and making any commitment," Roemer said. "It lessens his excellence. It will hurt his campaign."Roemer also indirectly skewered Rick Santorum, who in last week’s GOP primary debate said that America was based on moral laws, and those come before the 10th Amendment."I listened to this debate in Iowa, and I heard a guy on the stage say this country ought to be run by moral law," Roemer, who has failed to land a spot in any primary debate, said, raising his voice to a shout. "This country’s run by constitutional law. Where are these people? Where are they?"
