Two of Clinton's most loyal supporters are expressing concern Wednesday night. Senator Dianne Feinstein warned that a protracted campaign could have negative dividends, and called on Clinton to explain her strategy from here on out.
Former Democratic nominee George McGovern switched his endorsement, saying it was time to get behind Barack Obama. After the toughest two months of the campaign, Obama is rejuvenated, while Hillary Clinton has some hard decisions to make.
Hillary Clinton told reporters Wednesday she had to lent the campaign another $6 million this month in order to stay competitive.
"It's a sign of my commitment to this campaign. It's a sign of how much I believe in what we're trying to do," says Clinton.
What Clinton is trying to do is find a way to win. That appearently means changing the number of delegates needed to secure the nomination.
As Barack Obama moves closer to the magic number of 2,025, Clinton's camp is saying now the threshold should be moved to 2,210 -- a number that includes the delegates from Florida and Michigan.
"All I've said is that you've got to figure out how to seat the delegates from Florida and Michigan that is a reflection of the vote that they cast," says Clinton.
Clinton said today if the rules committee votes down that idea her supporters will take it up with the credential committee.
"Having a fight at the convention over credentials is the last thing the Democratic Party needs," says ABC Political Analyst Bruce Cain.
Cain says Clinton is playing a politically dangerous game. If she continues to attack Barack Obama, she could drive superdelegates to end the contest early, rather than let her continue to damage the party's likely nominee.
"There will be a temptation to come out early and end it because of the bitterness of the past three weeks," says Cain.
On Tuesday night, Barack Obama laid off Clinton and went after John McCain.
"We can't afford to give John McCain the chance to serve out George Bush's third term. We need change in America."
Will Clinton lay off Obama? Assemblywoman Fiona Ma, a Clinton supporter, doesn't think so.
"People understand that this is a very competitive race and things are going to be said. Hopefully they are true."
Obama's campaign finance chair in Northern California says it really doesn't matter to Obama.
"As Senator Obama has said, we're just going to play this out to the end and hopefully, we'll get to the magic number sooner rather than later taking nothing for granted."
Senator Clinton held a fundraiser in Washington D.C. Wednesday night and raised $1 million and told her audience she's in the race to stay. On Thursday, she has events in West Virginia, Oregon and South Dakota.
