Looks like Tester for Montana! Virginia still in play. If Virginia stays blue, then they are 49 Democrats, 49 Republicans, 1 Socialist (figure as Democrat), and 1 Lieberman (treat as Republican) in the Senate.
I think Firedoglake has it right, when they predict Lieberman will position himself for some major worship to tip votes the Democrat's way. Else, deadlock, with ties decided by Cheney.
