Depends on where they turn out (e.g., which state, district, etc.).Two things bother me the most about this election, besides the historical mid term stats:
Democrats outvoted the Republicans in the Presidential race 2016 by roughly 3m votes.
And 45 incumbent Republicans are not running in mid terms.
Hopefully will wake up on Nov 7 as surprised (pleasantly) as on Nov 9 2016.
I could care less if 3 million more Dems turn out in San Francisco, won't change the outcome. Was gonna be Dem anyhow.
