Who did you vote for this time around?
I used to just vote for any nutjob who wasn't with a major party, but now I vote for whoever appears to be leading among third party candidates. And really, ideology has NO bearing on my vote. I'm just trying to increase the votes for the other people. If enough Americans do this, the third party candidate never has to win in ordder for the major parties to see they're losing votes and change in order to recapture those votes.
That's my approach anyway. And really only for national elections because they aren't as immediately impactful as local elections. And partisan ideology doesn't seem to be as overbearing in local politics.
