Current stats show the most likely outcome to be a 52 D / 48 R split.(Two of the D's are actually independents who caucus with the democrats - Sanders, and Lieberman.)
However, two races are going to play a pivotal role here - West Virginia, where the Democrat Joe Manchin recently took a small 2 point lead over the republican Rease, and Washington state, where the republican Rossi is in a statistical tie with liberal Patty Murray. If these two races flip to the republican column on Tuesday, the senate will end up in perfect, 50 / 50 split. Democrats would still keep the majority, and Vice President Biden would cast any tie breaking vote.
