Report: Clinton Preparing to Drop Out

Thomas Edsall has posted on Huffington Post that Hillary Clinton has summoned top donors and backers to her speech in New York tomorrow night, which is being regarded as a sign that she will drop out. He notes that Clinton staffers were being urged by the campaign's finance department "to turn in their outstanding expense receipts by the end of the week." He also writes that negotiations are underway between the two candidates' campaign staffs on post-primary activities:

In addition to seeking Obama's help in raising money to pay off some $20 million-plus in debts, Clinton is known to want Obama to assist black officials who endorsed her and who are now taking constituent heat ...

If wonder if Rep. Stephanie Tubbs Jones (D-Cleveland) might want Obama to help her protege State Rep. Eugene Miller (D-Cleveland), who has been a loyal Clinton supporter to his detriment in a heavily African-American district, when Obama is in town (which should happen frequently).

UPDATE: A long-time Clinton supporter, former Iowa governor Tom Vilsack, said today that it is time for Clinton to back Obama. And Ben Pershing writes on the Washington Post blog Capitol Briefing that the seventeen uncommitted superdelegates in the U.S. Senate (which includes Sen. Sherrod Brown (D-Avon)) are meeting this afternoon, with CNN reporting that most of them will endorse Obama tomorrow.
