For a little while there, it looked like Hillary Clinton had a shot at mounting a comeback. But on Tuesday, that pesky math caught up with her. There's simply not enough time, or delegates, remaining for her to pull it out. Barack Obama has won. Such is the prognosis from all of those but the most hardened loyalists. Here then, a compendium of obituaries for Hillary's '08 bid for the presidency.

First, a few editorials from today's papers:

The Seattle Times gives us "Clinton's end: time to yield and unify," that conculdes:

Clinton's campaign is over. She is perhaps the last to know.

Today in Superdelegate news:

A defection. Virginia's Jennifer McClellan, who had both previously endorsed Hillary Clinton, has now jumped ship (along with George McGovern) and supports Barack Obama.

Clinton picked up Rep. Heath Shuler (N.C.), and Indiana Rep. Brad Ellsworth. Clinton won both of their districts yesterday.

Obama also got the nod from N.C. State Democratic Party Chairman Jerry Meek, and from Jeanette Council, also formerly undecided from N.C. And then came word that California's Inola Henry has declared for Obama.

Shuler and Meek cancel each other out, leaving Coucil and Henry as unmatched pick-ups, but because McClellan pulled their support from Clinton (-1 for Clinton, +1 for Obama), the net gain for today stands thus:

Obama 4, Clinton 1.

The first big superdelegate name to declare in the wake of Hillary Clinton's disappointing showing last night. Get ready. The flood is coming. Barack Obama heads to Washington D.C. tomorrow to talk to uncommitted superdelegates.

No doubt there are more than a few supers who'd like Hillary to make their decision a moot point. Geroge McGovern, the former Senator from South Dakota, as well as a former Hillary supporter and friend of the Clintons, doesn't appear to be content to wait.

McGovern had previously endorsed Clinton, so that means a loss in the superdelegate column for Hillary, and a pick-up for Obama. The message is pretty clear.

An e-mail from my colleague Liza Porteus Viana details McGovern's call-in appearance on MSNBC:

Not sure if you heard McGovern,

"I think the mathematics indicate Senator Obama is probably going to be the nominee. I have no regrets about Senator Clinton... but I think the time has come for democrats to unite and to get ready for a tough race this fall against Senator McCain. And that's why I'm hopeful that Senator Clinton will see fit fairly soon..."

He talked about his conversation with Bill Clinton, during which he announced his intention. Bill "of course wishes I had stayed with HIllary." But "we didn't have one single angry word." Bill did not admit Hillary's chances are next to impossible. "He recognizes it's a tough race but he didn't express any of those views."

Thanks Liza!

Update: Clinton gets a super of her own, post Indiana./N.C.
