Possible. I'd argue the reverse is more likely, given that people relatively uninterested in voting are disproportionately less likely to be partial towards a particular candidate or cause or otherwise interested in changing the status quo.

Reasons for not voting vary. Uninterested voters are common, but other factors (didn't like the candidates, forgot to vote, too busy, transportation problems, inconvenient polling place) show up too.
