If Hillary gets remotely close to securing the nomination, or if she does, Evan Bayh will be named her VP candidate. He helps win votes in a red state, brings a Midwestern flavor to the ticket (since Hillary disowns her own roots except when she's, you know, campaigning in the Midwest), and he's been used to offer a moderate dimension to the national Democratic scene before (see the DNC from a few years back).
In doing so, Bayh would finally receive the national PR he needs to make a legitimate run at the White House - his campaign stalled early on this year, but I think it's interesting that he still dropped out earlier than what most expected. Maybe it was some early signal calling on the Clinton campaign's behalf; they did, after all, anticipate having the election wrapped up by Super Tuesday.
