David Broder: " On the Democratic side, the battle is more even, but the advantage has shifted back to Barack Obama - thanks to a growing but largely unremarked tendency among Democratic leaders to reject Hillary Clinton and her husband, the former president." This is true of Democratic and liberal-leaning elites who reside along the Northeast Corridor. But is it true of Democratic voters in general? Not really. Since the Iowa loss, Clinton has mobilized winning coalitions of voters in New Hampshire, Michigan, Nevada, and Florida. Yes, I know Michigan and Florida don't count (at least not until the Clinton campaign strong-arms the DNC into awarding those delegates). But won't Super Tuesday resemble, in some sense, the Michigan and Florida contests? That is, so many states will be voting, so quickly, that it is hard for any candidate to campaign effectively, difficult for the campaigns to build up additional grassroots support. So the results likely will turn on name identification and traditional coalitions of Democratic voters. That's a scenario which favors Clinton. Obama needs a game-changer if he is to score what would be one of the greatest upsets in the history of American politics.
