FROM CNN's Jack Cafferty:

Another day closer to the slow, painful, but inevitable end that seems more and more to be staring Hillary Clinton square in the face. Barack Obama has now drawn almost even with Clinton among the superdelegates.

Three months ago, Clinton led Obama by more than one hundred superdelegates. Now her lead is down to 28. Since March 4th, 17 superdelegates have publicly announced for Obama while Senator Clinton has actually lost one. They include New Mexico Governor Bill Richardson, Pennsylvania Senator Bob Casey, Minnesota Senator Amy Klobuchar and Wyoming Governor Dave Freudenthal, who had been appointed the state's U-S attorney by Bill Clinton. Plus former President Jimmy Carter - who won't disclose who he's backing, but strongly hints that it's Obama.

Some Clinton supporters are now suggesting that she needs to top Obama in the popular vote in order to have any chance of winning.
