He has bagged another. Wyoming Governor Dave Freudenthal. This is the 65th superdelegate he has won since 'Super Tuesday'. Don't know exactly Hillary's count but it is in single digits.

He has closed down her lead to single digits in Pennsylvania with some polls even giving him a 2 point lead.

"Obama overtakes Clinton in PA
Raleigh, N.C. – Barack Obama has taken the lead over Hillary Clinton 45-43 in
Pennsylvania, according to the newest survey from Public Policy Polling."

She has 11 million in the kitty for the rest of her campaign - this is BEFORE she has settled the 8 million debt she has run up, excluding the 5 million she loaned. Her afluent supporters have maxed out on their contributions and she does not have a significant 'small donor' base to help her through. Another thing that has got to be at the back of her mind, is that she has to contest her senate seat in 1 or 2 years from now and will be neading a good deal of money for that.

He has 31 million in the kitty and no debt.
This has allowed him to spend over 2 million in ads not only in Pennsylvania but in North Carolina and Indiana as well. In contrast, she has only been able to spend 400,000 odd in Pennsylvania.

Whatever drives the stake through her, be it pledged delegates, popular vote, superdelagates or simply just running out of money - her race is over with Pennsylvania her swan song.

She can't win...legally. The Clintons are trying, without much success, to pressure super delegates into voting for Hillary, but the opposite is actually happening and more and more of them are either endorsing Obama, or simply saying nothing, which means in most cases they'll vote for Obama when the time comes.

Hillary knows that it's over, but there are two real issues for her. 1) Staying in the race long enough to get back the money she 'loaned' to her campaign. 2) She believes that Obama "can't win" against McCain because he's black.
