Why The Superdelegates Won't End It

Because nobody can make them, says Jeff Greenfield:

...who are the brokers? Which political leaders can deliver pocketfuls of delegates? The short answer is, no one. The undecided superdelegates control exactly one vote each (or half a vote)—their own. The idea that a cohort of these folks will unify calls to mind the difficulty of herding cats. To be sure, dozens of House superdelegates will listen to House Speaker Nancy Pelosi, but the politics of their districts—or their key financial supporters—are likely to matter a lot more to them. As for National Chairman Howard Dean, his office comes with few if any powers of persuasion. Even its fundraising pales in comparison with the party's senatorial and congressional campaign committees, and Dean's political clout has so far proven nonexistent. Al Gore clearly has the respect of his party, but many of the brokered convention fantasies revolve around him as the ultimate nominee, not kingmaker.

Because they don't want to, says John Podhoretz:

Yes. Sure. Because politicians with the most valuable votes in America are just going to choose up sides and not spend three months being courted and feted and promised. They are going to forswear having their feet kissed, their backs massaged, their views requested, their wants fulfilled, their needs anticipated. They are going to throw their vote away rather than milk it for all it’s worth.

... The point here is: A thousand or so people are going to decide this primary. It behooves those people to have this go on as long as possible, because that is how they are going to get the most goodies. Maybe this is what Hillary truly understands.
