I would just like to point out that there is no actual way the Democrats win control of the Senate. If they did actually win the Senate they would win the only two competitive GOP-held seats (Arizona and Nevada) and then they'd have to pick up a safe GOP state (Texas, Tennessee, Wyoming, Mississippi, Nebraska, Utah). There is no actual chance that the Dems would be able to pick up those seats. If they were to win Nevada and Arizona then it would be a 50-50 tie with Pence giving control to the GOP. The math absolute trash for Democrats. Expect a big gain for the Republicans

Anything could happen. Don't be so arrogant.
It's really difficult to predict anything when we don't know who the candidates.
