I think Biden and Palin may have helped a couple of points in their home states, but it helped that they had statewide office in a small state.
Yeah, but not by much:
Delaware had been trending Democratic for a while, and Biden as VP only amplified the trend. Palin put a big damper on Alaska's swing towards Obama (the other mountain west states swung towards Obama by much bigger margins, with the curious exception of Wyoming).
The last time a VP made a big enough difference to swing their home state was probably 1996.
