Roger L. Simon has the full write-up here:

What’s interesting on quick evaluation is that no Republican seems to have made his or her way to a substantial lead. Rick Santorum and Condoleezza Rice are the only candidates, potential or otherwise, narrowly defeating Obama at this moment.

But the news is not good for the President either. Besides the fact that several candidates (Romney, Chris Christie, and Jeb Bush) trail him only within the margin of error, as you will see in the cross tabs tomorrow, Obama scores abysmally among independent voters.

More here, and more to come tomorrow.
