Her lead is still within the margin of error at 47/43, but that’s up from 45/44.

The details…

No ground really gained or lost by either candidate after Wednesday’s debate. The one day sample had Clinton leading by 4 points.

She is solid with Catholics, whites, Hispanics, and older voters. Obama holds his strong support among African Americans, the young , and Very Liberals.

What is very significant here is that when we ask these likely primary voters who they would vote for today in the general election, Clinton scores 75% to 9% against McCain, while Obama leads McCain 72% to 14%. The difference? Only 11% of Catholic Democrats and 12% of white Democrats choose McCain in the match against Clinton, while 22% of Catholic Democrats and 18% of white Democrats choose McCain against Obama.”

There was a shift in the genders. Among men, Clinton made up seven points in the last 24 hours against Obama, who still holds a 49% to 41% edge. But Obama also made up a little ground among women, where Clinton now leads by 13 points, down from 15% in yesterday’s tracking poll.
