And so it begins.

She alienates the very Superdelegates she's been crowing about:

The Clinton campaign has been actively wooing these delegates, believing a plurality represents the strongest, and increasingly the only, way for her to win the nomination. But one undeclared delegate, who spoke on the condition of anonymity, said the recent tactics are turning her and other superdelegates off.

"I don't think anybody's saying 'step aside,' but 'stop with the garbage' is what people want to say," the delegate said. "Just chill a little bit."

As activists committed to the party, they said, they have been impressed by Obama's ability to bring new Democrats into the fold, and they worry that Clinton is threatening that.

"We like the fact that there is a candidate that has won so many states overwhelmingly," the delegate said. "We're feeling her advisors are leading her in a path that diminishes her as well as him."

Several said they were angered by comments from James Carville, who called Bill Richardson "Judas" for backing Obama after serving in the Clinton White House. One delegate said Richardson's rationale for supporting Obama, and his implicit frustration at the Clintons' heavy-handed approach to garnering his support, was echoed among superdelegates.

Her oligarchical backers threaten the sitting Speaker of the House, Nancy Pelosi:

Pelosi has not publicly endorsed either Clinton or Barack Obama in their hotly contested White House battle, but she recently said superdelegates should support whoever emerges from the nomination contests with the most pledged delegates -- which appears almost certain to be Obama.

Among the signees of the letter were prominent Democrats and Clinton supporters like Robert Johnson, founder of Black Entertainment Television; Bernard Schwartz, former chairman of Loral Space and Communications; and venture capitalist Steven Rattner.

The signees reminded the House leader from California of their support for the party's House campaign committee and said "therefore" she should "reflect in your comments a more open view" about superdelegates.

Smart to do with arguably the most powerful woman in American politics?

And the public agrees -- her support is starting to melt:

Democratic presidential candidate Hillary Clinton's positive rating has dropped to a new low of 37 percent in an NBC/Wall Street Journal poll released on Wednesday.

According to the poll, the New York senator's positive rating slid 8 percentage points in two weeks and she had a negative rating of 48 percent in a week where she admitted making a mistake in claiming she had come under sniper fire during a 1996 trip to Bosnia.

And what's best for America?:

When asked which candidate could unite the country if elected, 60 percent said Obama, 58 percent said McCain and 46 percent said Clinton.

Meanwhile, does Obama maybe really have a chance in Pennsylvania?
