trump had no chance in va because of vp pick which gave her a boost in the state.
Doubtful. Like Yank says, Trump is a poor fit for Virginia. High proportion of white Republican-leaners with bachelor's degrees relative to non-college-educated Obama voters. Vice Presidential nominees don't seem to have much of an effect unless they're spectacularly popular.
True, but Kaine is popular enough that he certainly won't hurt Clinton in VA, and he might help increase her margin slightly (not that it will make the difference). In contrast, Pence is unpopular enough in Indiana that he probably won't help Trump at all and may even hurt him a bit there.
