I hesitate to share this because it reveals how unhinged the midterm elections have made me. But here’s a spreadsheet of 70 House districts that could conceivably go either way in tomorrow’s vote.

To win a majority of the House of Representatives, Democrats will have to carry 33 of these 70. Nearly half. That is, they need to hold the ten Democrat-held districts listed here, and take 23 more.

After an unhealthily obsessive study of polls and coverage, I’ve given each of the 70 districts a score.

• If it looks like a likely Democratic pickup, it gets a 1.
• If it’s too close to call but I think it’s a plausible Democratic win, it gets a 0.5. That way, every two “plausible” districts equals one Democratic pickup.
• If it’s a longshot, it gets a 0.
• If it’s close but there’s a plausible chance that a Democratic seat could flip Republican, it’s a -0.5.
• If the Democrat is likely to lose, it’s a -1 (that’s Radinovich’s seat in Minnesota, and a result of court-ordered redistricting in Pennsylvania-14).

I’ll update this through election night. But as of 5:00PM on Monday the 6th, I see the Democratic Party just barely squeaking by with a net gain of 23 seats, giving them a bare 218-217 majority:

You may score these districts more optimistically than I do. But I’ve been burned before, and by my reckoning, the Democrats will just barely make it.

Most analysts seem to be expecting the Democrats to pick up about 35 seats. (I’m closer to the RealClearPolitics map, which predicts a 26.5 seat Democratic pickup, for a 221.5-213.5 majority.) Sorry, but I just don’t see 35 seats.

There’s no wiggle room. This spreadsheet explains why I’m feeling pretty anxious about the Trump administration being subjected to any meaningful oversight and accountability over the next two years.

If I’m wrong and it’s a blowout, I’ll be delighted to admit how cracked my crystal ball is on Wednesday.
