Here are some of the "myth-busters" presented on this morning's conference call with Clinton chief strategist Mark Penn: 1. Obama may have had momentum in the last week, but yesterday, Clinton won more voters who made up their minds on Super Tuesday itself. 2. Clinton actually won the youth vote in two states -- Massachusetts and California. This is significant news, since most experts have assumed that Obama's youth appeal cuts across geography, race, class, and ethnicity. In California, where Latino voters made up a good proportion of the young, Clinton won under-30s by three points and 18-24 year-olds by six. In Massachusetts, it was really more of a tie among all under-30s, with Clinton winning 49 to 48 percent. But shockingly, in a state filled with progressive college students, Clinton won the 18-24 age group 57 to 39 percent. I hope there will be more analysis from youth vote experts on that stat. Head-spinningly, Obama reversed the margin among 25-29 year olds in Mass, winning 59 percent of them. It could be that the 18-24 demographic just wasn't as dominated by students as one would expect, and that turnout was higher than usual among non-college youth. 3. In Missouri, Clinton proved she can win rural voters, Penn said. --Dana Goldstein
