In recent days, Obama and Edwards have traded mild rebukes to differentiate themselves. Still, their strategies fall along the same lines: To become the singular anti-Clinton candidate, win over undecided Democrats and become the "second-choice" among those backing others who won't get enough support on caucus night.
"This, I think, is going to be more of a horse race to the finish among the three horses who have been in the front for quite a while," said Obama adviser David Axelrod, who, ironically, served as a strategist for Edwards four years ago.
Even mild criticism dished out at this stage of the campaign, with little more than two weeks before the Jan. 3 caucuses, represents the tightness of a contest that finds Clinton, Obama and Edwards atop polls in Iowa.
