I'm thinking quite a few and that heavy Republican turnout in some instances could be to vote AGAINST their own nominee, platform and campaign issues. Food for thought. My understanding of the far right is that it is a consistent 23% of the electorate (give or take). That's roughly half of the Republican Party. Does the "sane" half stay Republican or break out and vote Democratic?
Sorry it's not a more fleshed out diary. The exit polling on Obamacare has given me some hope.
