Clearly Republicans are going to pick up Oregon and California while Democrats pick up South Dakota and Tennessee
Obviously you must mean the Tennessee Senate seat. The Democrats are not going to pick up the Tennessee governorship.
With that caveat you never know.
Continued violence like that caused by Antfia may eventually cause a backlash.
Continuously raising taxes often causes a backlash. So will the paying healthcare for illegals as their numbers continue to rise.
I mean the gubernatorial race, sarcastically. Democrats are not going to win TN-GOV and SD-GOV is a real longshot. And if they did somehow win both, there's no way that they'd lose OR-GOV and CA-GOV at the same time. Basically, I was saying that it was a ridiculous idea.
And if there's going to be a backlash, I'm pretty sure Trump's election is going to cause (if it hasn't already) a much larger backlash than Antifa would.
