Richardson's edgy, opinionated and at times risky high-wire campaign has gained him double-digit poll numbers in the first primary state, New Hampshire, where he has begun to attract endorsements from key local Democrats and favorable reviews from the state's influential newspapers. One recent New Hampshire poll put him ahead of John Edwards. A summer survey of Democrats in the first caucus state by Iowa's Des Moines Register had Richardson in front of Barack Obama and just five points behind Hillary Clinton as the choice of the most likely caucusgoers. In Nevada, another early caucus state, Richardson's support has grown from 2 percent in March polling to 11 percent in August.
I don't think Richardson's experience/ resume is a minor thing, it is the most important thing. He has stronger experience by far than the other 3 top dem candidates and if they were the nominee, they would struggle because of their lack of executive and international experience.
