Senate Up for Grabs?

This poll summary by the folks at Rassmusen predicts a 48/49 Democrat/Republican split with three races just too close to call. Democrats would have to run the table on these tossups, but the idea of a 51 seat Democratic caucus no longer looks like a moon shot.

In other news, Rhode Island really looks like a likely pickup for Dems, as incumbent Republican Linc Chafee is in a world of hurt against Sheldon Whitehouse in their latest poll.
