Democrats won't recover the senate until 2022

[Hindsight was 2020]

Depends if somehow Foster pulls out the upset in Louisiana then game on for 2018 but in all likely hood the best case for the dems is retaking the house, winning governorship in FL, NV, MI, WI, MN and cutting the senate to 51-49

If 2022 is a Trump midterm, with 6 more years of demographic movement, the Senate is practically likely D.  PA+NC+GA+FL+AZ+AK should be very doable by then.  Even in a worst case scenario where they only win Clinton states in 2018, that should be enough.

Yes. But - probably not sooner. In 2018 Senate map is atroccious for Democrats and Trump (most likely) will be not too unpopular (it takes time to get there). In 2020 states like AZ and GA will still be at least Lean R. By 2022 - possible.

Trump is already unpopular it's very and in my opinion likely he will be toxic in 2018

The thing dems got for them is I can completely see Trump turning his venom on his own party if they fight him on trade wars and his cabinet picks and seeing as Heller and Flake are two of his biggest critics an going in Twitter rants telling his followers to vote third party or not at all
