By the way, with - I think - four states yet to be decided, Republicans picked up a net gain of 9 governorships. The only states that switched from Republican to Democrat governors was Calif. and Hawaii. So far 12 have switched from Democrat to Republican.
The NY Times is publishing a map, online, of the Senate, House, and Governor race results. Showing red for Republicans, blue for Dems, and grey for Independents, etc. Notice the map for the House/Congress race results so far. Notice the strange shapes of a lot of the districts. Also notice that the striated pattern indicate a "pickup" or switch of parties in that district. I find quite a few that switched from Dem. to Repub. I can find none that switched from Repub. to Dem! You can go to the top of the page and click on similar maps for Senate and Governor race results.
