Final post of the day-- The polls close in Mississippi at 8:00 but the networks do not call the state for Obama immediately. Takes them about 20 minutes. Can't tell the margin exactly, yet.

Out in California, as commentators and panelists discuss on MSNBC--Olbermann and others--Geraldine Ferraro has followed up on her historic comment about how only a black guy could be in Obama's successful position, right now. She then retorted to critics that she is being attacked because she's white.

Howard Fineman makes some good points on this, responding to questions about why the Clinton campaign does not repudiate the Ferraro remarks and fire Ferraro as a fundraiser--basically, that the Clinton campaign does not want to. It wants to make the 'kitchen sink' bigger, not smaller. He may be right.

Someone quotes James Carville as saying that the state of Pennsylvania is basically Pittsburgh and Philadelphia, with Alabama in between. Somewhat disheartening, if the Clintons are seriously counting on racism in rural Pennsylvania as their firewall.

Chuck Todd seems solid on the delegate numbers. It is virtually impossible for Clinton to reach the 2025 total. But Obama could do so, even if he gets only 46 percent of all remaining delegates.

That wd argue for the Clintons' not engaging in scorched-earth tactics . . . Obama is going to be interviewed by Chris Matthews at 10:00 Eastern.
