4. What did the exit polls show about the 2017 elections? Back in 2016, President Trump was able to generate a big turnout of White Republicans. In 2017, it looks like Democrats were able to get their people to the polls. This is a simple kind of game - it's called turnout. The exit polls in Virginia showed an electorate that was identical in makeup to 2016 - 67% White, 21% Black, and 6% Hispanic. 2018 will be another election that boils down to a simple matter - which party can motivate their voters to get to the polls. Usually, mid-terms excite the party that is not in power in the White House. And just as Republicans used the Obama health law and his agenda to motivate their voters in 2010, Democrats will try to do the same in 2018.
5. A message on the Obama health law from Maine. Voters in Maine left no doubt where they stand on the issue of expanding Medicaid coverage under the Obama health law - they were strongly for it, as a statewide referendum went in favor of that Medicaid expansion by a 59-41 percent margin. That's not a small victory, in a state where the GOP Governor was against the idea. It's also a reminder that despite a lot of Republican efforts over the last seven years, they still can't get rid of the Obama health law.
A lot could happen in the next year. But for now, Democrats seem to be on offense, and the GOP is playing defense.
