Re: The 2018 midterm elections!
Dem control of the House is likely. Dem control of the Senate is quite unlikely...until recently.
Dems appear to need two additional senators beyond those that appear likely. They need to keep the following states that lean Dem:
AZ Simena
NV Rosen
MO McCaskill
Take the toss ups:
ND Heitcamp
FL Nelson
And take one of the following lean GOP:
TX ORourke (which seems like a long shot)
TN Bredesen
Most have seen positive polls over the last few days (McCaskill being the exception)

The recent developments of 1) Trump's ever sinking popularity for anybody not already in his cult, and 2) Kavanaugh turning into a liability almost overnight for the GOP vs an asset are certainly making the picture brighter. I think of it like this: going into election season there were 10 seats in Chump won states vs 1 Clinton won seat up for re-election. As of today 4 of those states (WI, MI, OH, PA) are not on even the GOP's radar for potential flips. Furthermore, people like Manchin and Tester are moving into the Leans D category.
That leaves IN, ND, MO, and FL. Personally I'm not as worried about Florida as pundidiotry is, although I'd feel a lot better if Scooby declared Gov. Scott to be a lock!

The medicare crook has had the airwaves to himself for months, and he's still tied in the polls with someone who just started going up on air. Furthermore Scott has never been that popular, barely winning his two races in very good GOP years. Put another way, if Florida flips, then a lot of other states are going to before that one and the GOP will be increasing their Senate majority.
I'm heartened that IN, MO, and ND are still even races because one would have thought at this point the challengers would have put a couple of those away already. Especially since those challengers are fairly generic R's and not Todd Akin types. However the Dems are either going to have to sweep all 3 of these races as well as NV and AZ, or trade ND for TN. If Ted Cruz goes down, then its the opposite situation of the FL race. Dems win in Texas and they're already having a very, very good night long before that race gets called.
