Yeah that's what I have in mind.
I wonder if coming out of 2018 with 52 Senators puts 60 in play for 2020.
Well, let's see.
Assume we start with 52.
Very good chance for a pickup
CO, Gardner's seat.
If Collins retires, we have an excellent opportunity in ME, especially with ranked-choice voting preventing the left from shooting itself.
We have a good chance in NC because Tillis only won narrowly in 2014.
Decent chance for pickup:
Iowa, if it snaps back hard this year and in 2020.
The second Arizona seat because McCain will in all likelihood be gone by then.
Kentucky, especially if Mitch retires. (He only won 53-47 in 2008.)
Iffy chance for pickup:
Montana if Bullock runs against Daines.
Hail Mary:
West Virginia if Ojeda runs against Capito.
Winning all of the above would give us 8 seats, BUT we'll probably lose Doug Jones's seat in Alabama, resulting in a net gain of 7.
So we'd end with 59 in the best-case scenario.
