New Senate polls due out in the morning from Mason-Dixon for McClatchy Newspapers and MSNBC. Word is things are very, very tight--at best.

Mason-Dixon's Montana poll is already out, showing Sen. Conrad Burns and Jon Tester tied at 47% apiece. That's down from a 7-point lead for Tester in September and a 3-point lead in October.

Update: In VA, Webb at 46%, Allen at 45%.
