Pick my chin up off the floor and start planning for the midterms, which, by the way, would be beautiful. The 2018 midterms would be absolutely beautiful.
Yes, we might even cut into their Senate majority by a seat if we can win Nevada! (Assuming we somehow hold Missouri, Montana, and North Dakota!)
Oh, governorships? WHO CARE! As if Trump won't issue executive action overruling them.
Since North Dakota will go Republican, and Sandoval and Heller will probably trade jobs, all Democrats have to do is pick up Arizona if Flake retires and have Doggett or someone similar beat Cruz. Then, Matheson could beat Morgan Philpot or Greg Hughes for the Senate.
That's a total of D+2. +Utah, Arizona, Texas; - North Dakota
As long as Toomey, Kirk, Johnson, Heck, Portman, and DeSantis all lose/McGinty, Duckworth, Feingold, Masto, Strickland, and Murphy all win, we could have a Democratic Senate from 2017 to 2021. Furthermore, only Feingold and McGinty have to win to get a 50-50 Senate if it's D+2 in 2018.
As easy as that sounds...
