A quick update on the latest polls, on the day before Super Tuesday.

Senators Clinton and Obama appear to headed towards a dead heat, with Obama gaining on Clinton in national polls and reducing Clinton's lead or moving slightly ahead in a few state polls, particularly California. However, Clinton still leads in most Tuesday primary states.

Today's CNN/Opinion Research Corp poll has Obama moving slightly ahead of Clinton nationally, though still within the margin of effor. Obama has erased Clinton's once sizable lead since South Carolina.

The CBS/NYT poll has Clinton and Obama tied at 41 percent each, nationally. However, as Josh notes, this poll has Clinton holding a large lead -- 49 to 31 percent -- in just those states holding primaries Tuesday.

From the Washington Post/ABC poll:

2/1/08 1/12/08 12/9/07 11/1/07
Hillary Clinton 47 42 53 51
Barack Obama 43 37 23 24

A Reuters/C-SPAN/Zogby poll Monday has Obama opening narrow leads in California and Missouri, and deadlocked in New Jersey, while holding larger leads in Georgia and two other states. A Quinnipiac poll in New Jersey shows the Clinton lead to be 48 to 43 percent.

Via John Aravosis, check out the trend lines from the Gallup daily tracking polls, which show a more or less steady climb by Obama relative to Clinton. The two seemed to have split the Edwards votes since his stepping out of the race.

We'll add more polls as we go along.

See you in the next thread.
