Ok people, GET A GRIP. It's just a fucking election.
70% or so of the people are straight party line voters. If they ran an ax murderer against someone who raped babies against a sane third party candidate, a huge chunk would *still* vote their party by rote. So don't get all bent out of shape that some people voted against a candidate you dislike.
The rest are swing voters, who can be persuaded to vote for one party or the other. They tended to support Obama two years ago and Republicans this time around. There are various reasons why that is, but note that where Tea Party candidates tended to *lose*, a more moderate Republican candidate was projected to win. This indicates that the Tea Party is something that certainly can't afford to be ignored, but that it does *not* represent a majority of the population.
Is it the end of the world that we have divided government? Don't be an idiot - we *usually* have divided government. *Nearly always* when one party controls the Presidency and both chambers of Congress they get hammered in the next election cycle. This is because the moderates tend to either get skeeved by what the wingnuts on the far side of the controlling party suggest and want a check on their power or because they think the party in power should have stepped up and used the power they were handed more wisely. It's a lot easier to blame someone for failure than to celebrate what they did.
The thing to keep in mind is that the "divide" between the parties is one of degree, and that's not a bad thing. It's not like a huge chunk of the electorate wants to re-enslave African Americans, or invade Mexico, or launch a socialist paradise [1] - but if you look at politics in other countries, issues that people in the states consider non-issues are critical. Look at the "kill teh gays" law in Uganda as an example.
So, just chill out, okay? While there is plenty to criticize, and there will be wackadoodles who pretend to speak for "the people", in the long run the country tends to do a pretty good job of not going completely off the deep end.
