If he does run, it won't be O'Malley's first rodeo. The presidential politics bug bit O'Malley early; When he was 20, he was traveling, he said, to all 99 counties in Iowa, and later New Hampshire, on the 1984 Gary Hart campaign.
That old Hart network could give O'Malley an early assist.
"The Hart people, I think more so than many other campaigns, have continued to stay in contact," he said. He said he's gotten more campaign contributions from Colorado than any other state other than Maryland as a result.
Dan Calegari, a former Hart operative close to O'Malley who has become a regular in presidential campaigns in New Hampshire, said many of O'Malley's old friends from the Hart network are prepared to work for him if he gives the word.
"If Martin O'Malley gets in the presidential race, I'd be the first guy out of the gate," Calegari said. "I hope he does it."
