Nevada's got a Republican Governor right now so they've won something. Tend to agree that it's a D tilt; it'll be a tough out, but beating incumbents is hard.
Cruz will win Texas by 4-6 points. He can only lose if he alienates Cult 45. He's already endorsed Trump so I am assuming he'll stay in line the next 10 months and it'll be a non-event.
Florida, I mean, there are some bright spots for Dems in the past 12 months if you squint but yeah I can't see it with Trump on the ballot.
Senate is a heavy R overall. I mostly agree with @Js1's assessment of individual races, though I'd move WV to Safe R. But those lean/likely D's include a few that are just slight leans, and FL-T are really likely R. Dems have to make sure they take no losses in AZ, NV, WI, MI, and PA; win tossup-at-best defensive races in MT and OH, and win the presidency. Long odds on a parlay like that. Lose even once in any of those and it's a GOP senate.
Biden and Schumer need to get busy with judicial vacancies.
