Monday Polling Crack

Mark Blumenthal:

If you hoping for (or dreading) indications of a clear shift in voter preferences on the surveys released in the last 24 hours, you will not find them here this morning. As of this writing, Barack Obama's margin has clicked up very slightly on our national trend estimate, while yesterday's statewide surveys show a very slight narrowing of that margin in a few key battleground states. However, our current classification of the states remains unchanged over the weekend: We still show 311 electoral votes for Obama, 142 for McCain with seven states representing 85 electoral votes still in our toss-up category.
