No idea who is stressing about the Senate going Diem, but anyone who does is silly. The Senate is most likely going to go +7 to +9 for the GOP in November. 23 Dem seats are up for grabs, and only 11 GOP seats. President Trump won 11 of those Dem states. Hillary won only 1 of the 11 GOP states. Current polling, even by the Lefty outlets, has the Senate going +7, meaning 58-42 GOP.
Hopefully we get the Limited Government Republicans in those new seats, and not more McConnell twits. But again, fretting over the Senate is either misguided, or just more attempts to motivate GOP turnout for the House and for state seats.
Remember...
Trump has no path to 270 electoral votes...
Clinton will win by at least 20 pts...
It aint over till it's over...
Just call me silly.
