Reality is choosing among possible paths as rapidly as it can but there are so many of them. We can simulate reality so much faster than reality can play out because reality does not simplify.
One of the things that we will learn is how unique is Trump. It is very normal for a Republican to win the presidency after two terms of a Democrat in the White House. In that sense, the 2016 election was boring and normal. But of course Trump is a bizarre character who seems to most of us to be hugely different than a typical Republican. If he really is, the backlash could be bigger than what is captured in current probabilities; if typical Republicans and swing voters think he is really no different than a normal Republican, there will likely be a swing towards Democrats but it won't be very dramatic; about enough to win the House but still be still be a minority in the Senate.
What is certain?
Democrats could win by 6 points nationally (53 to 47) and still lose the House. Because of gerrymandering and the fact that individual voters in big cities have less influence even in House races, Republicans have about a 5 to 6 point starting advantage for Congress. That strikes me as the most remarkable thing about politics in this second decade in the 21st century.
Related, the counties that voted for Clinton represent two-thirds of GDP. It is the areas of the country that least understand how to create jobs and wealth that thought Trump's anti-trade, anti-immigrant, nationalist agenda sounded like a good idea.
As it now stands, our policy is being decided by minorities as counted by the number of voters and GDP. That's certain. And that is certainly weird.
What else is certain? The House will decide whether we learn what Mueller has learned about Trump. The House will decide whether Trump will - for the first time in his life - experience any negative consequences for any negative deeds. Voters today will decide whether we continue to have a Republican-led House that merely enables Trump or a Democratic-led House that checks his worst excesses.
What is certain is that Trump will be more dangerous with a Republican-led House. I'm certain that I don't want two more years of a Congress that merely acquiesces to his every whim; I wish I could be certain we'll get that.
Finally, as I think about today's election, the words of Tiny Tim repeat in my head: God bless us everyone.
