Here are the most recent results for many states:
California (Zogby Feb 2):
This is the first poll to show Obama ahead in California, and it tends to confirm what the Clinton camp has privately acknowledged, California is tightening.
New Jersey (Zogby Feb 2):
Georgia (Zogby Feb 2/Mason-Dixon Feb 1:
Alabama (Survey Jan 31):
Missouri(Zogby Feb 2/Mason-Dixon Feb 1)
Connecticut (Survey Jan 31):
Arizona(Mason-Dixon Feb 1):
Colorado and Minnesota also look like close contests.
Obama has a massive lead in his home state of Illinois, Clinton a large, but not as decisive lead in New York. These two states could cancel each other out delegate wise.
A couple other state, where Clinton has a large lead, but basically there is a realistic scenario where Super Tuesday settles nothing. All things being equal, Clinton will probably get more delegates, but not enough to to appear inevitable. Should Obama take California, the psychology of that victory may reset the entire race. Interesting article here that outlines why time might be on Obama's side.
Also, there is a new, well respected, national poll released today, confirming a very tight race:
Days before nearly half the country votes in the Super Tuesday primaries, Hillary Clinton and Barack Obama are locked in a tight race for the Democratic presidential nomination, their competing themes of experience vs. change now precisely dividing their party.
Should be a fascinating night.
