2008 Race Rankings: Mind The Gap

Beginning now, we're going to rank both the Democrats and Republicans each week. Look for new GOP rankings in a few days.

These rankings are ordered by likelihood of winning the Democratic Party primary and are based on a number of factors, including organization, money, buzz and polling. Click here for the old Republican rankings.

1. Hillary Clinton -- The margin between Clinton and Obama is as narrow as it's ever been. She's ahead because there's a plausible scenario for her to win the nomination even if she loses Iowa and New Hampshire; that scenario does not exist for Obama. Still, the tide is moving in the wrong direction for her.
