There were 9 battleground Senate races on the ballot last night in states that also had gubernatorial races. We may wind up with *5* split tickets out of that (NH, WI already, maybe GA, AZ, NV) and that doesn't count PA or OH where the same party won but with a big gap in margin. https://t.co/ZP6RhH8aaT — PolitiTweet.org
