Good summary here of how much ground was really gained last Tuesday. The biggest gain was perhaps a net gain of seven governorships. The GOP previously held a big margin with 34 governorships (I thought it was 33, but according to this article it was 34). In any case, Republicans are now are down to a margin of 27-23 governorships. IMO this is of more significance than taking the US House.
Democrats also have picked up six state legislative bodies, but Republicans were so far ahead on that count that they still have a 61-37 edge.
According to the article, Democrats now have a 225-200 edge in the US House, with 10 seats still undecided.
In 2016, Donald Trump won PA, MI, and WI, all traditionally Dem states. All three now have elected Democratic governors. Not a good omen for Trump's chances in 2020.
The article also notes continued increased polarization, with MN as the only state having one chamber controlled by Democrats, and one by the GOP. In every other state, one party controls both chambers (not counting Nebraska). With gridlock expected in D.C., the real action may move to the states.
In summary, this was a good cycle for Democrats, but there is still some catching up to do before we see the '
Emerging Democratic Majority' predicted by Judis and Teixiera now 14 years ago.
