It is highly unlikely that Specter's winning would mean the difference between having the senate in GOP hands or not. Most likely the GOP will net gain a few, how many depends on how good november is for us... the odds of the PA race being in the margin are miniscule, and in any case Toomey is more electable than Specter so if that is the concern you should vote Toomey.

Why then are Bush and Santorum endorsing Specter and not Toomey?
