Our own John Heilemann visited the Morning Joe crew today to discuss this week’s column about why Mitt Romney seems to be avoiding Iowa this political season, and whether that’s due to the thumping he took there in 2008. “[The Romney campaign] has been trying to maintain a rigorous distance from Iowa all along,” Heilemann said. “Because they did not want to raise expectations about him playing there.” Now, after coming in just behind Herman Cain in a recent poll in the state, Team Romney is obviously looking more favorably upon the Hawkeye State, but Heilemann warns: “The moment they decide they are going to run in Iowa full bore, the question then becomes, ‘Can Romney slay the demons of 2008?’”
