It's also 2 years from now, and expecting everything to be the exact same as it is now is utterly asinine.
It's like expecting a red wave in 2018 because of Trump winning in 2016.
Point taken in some states, but most of the states where Republicans are on the ballot are NOT going to realign in two years without some massive demographic shifts.
Look at that map. Iowa, Colorado, Maine. Those are plausible. Every other state with red on it is a solid red state.
--Texas *might* be in play if they can find somebody solid to run against John Cornyn, but frankly Cornyn is more popular than Ted Cruz.
--Georgia, possibly, but given what just happened down there, I think we can safely assume that the nation of Georgia has cleaner elections than the state of Georgia.
--Eastern Kansas went blue the other night, but that's unlikely to be enough to unseat Pat Roberts.
--North Carolina proved that any talk of us being a "progressive South" state is bullshit. Thom Tillis will get re-elected, and I doubt the local Democrats even have anybody worth a damn to run against him.
--Arkansas seems to have retreated back into solid red territory
--Arizona is in the realm of possibility, but they need a strong candidate
Now, if you're talking the Presidential election, sure...things can change. But I've learned long ago not to have any faith that the national Democratic party can avoid punching itself in the dick, because I'll invariably be disappointed.
