What if we concede the NH and IA primary and caucus to Sanders?

22. I'm unaware of these polls.

I can certainly see how some big-scandal or revelation could make someone abandon a candidate they'd previously chosen. But it's difficult for me to imagine that the "bandwagon effect" would be able to have the same effect on someone who's already made a decision.

What seems more likely is that if someone is still undecided, at such a late date, then they're likely to be the type of voter who can be more easily persuaded by the bandwagon.

If someone can be influenced by the bandwagon effect, then that's a voter that likely sees both candidates as being equal in all ways. It's a voter that truly cannot make up their mind and the bandwagon effect is just enough to tip the scales.

Or, the other type of voter who's likely to be so influenced is the low-information voter who really hasn't been paying much attention. Lacking information on the candidates, this voter ALSO see the candidates as being comparatively "equal" (even though the voter hasn't actually done any comparison.)

As a result, this voter lets others decide for him/her. They're inclined to "choose" a candidate based on perceived electability and that candidate's most recent victory. Perhaps this voter is thinking "everyone likes a winner" and who doesn't want to be on the "winning team"?
