Here's the score from the new batch of Mason-Dixon Senate polls: Republican incumbents Santorum, DeWine, Chafee, Burns, and Talent currently trail. There's your five seat pick up for an evenly divided Senate. Corker has moved slightly back ahead in Tennessee, and Allen is holding a small but steady lead in Virginia.

On the Dem side, Cantwell has extended her lead in Washington and Menendez is maintaining a slight edge in New Jersey, though he's stuck around 45% with eleven percent undecided.

It's possible Dems could tip either Tennessee or Virginia (or both), and end up taking control of the Senate. On the other hand, with Allen stabilized and Harold Ford, Jr. undergoing a bit of a late stage meltdown, it seems to me a more likely possibility that Republicans hold TN, VA and Talent squeaks by in Missouri, leaving the GOP with a razor-thin majority.

And there's also still a chance that Conrad Burns pulls out his race in Montana or Kean, Jr. scores an upset in New Jersey, which could reduce GOP losses to just three seats.
