Vote better voting first. Any kind of preference polling would open the door to actually party reform and 3rd party viability. Ranked Choice Voting (fairvote.org) or anything other than first past the post as we mostly have now is a huge improvement.then vote 3rd party first, followed by the lesser of the old two evils. In no time that 3rd party will be a top contender, but only once we fix our voting system.
