They won't control the Senate after this year's midterm elections, but I'm not so sure about the House.
I thought the conventional wisdom was the opposite, no? That the House, even as gerrymandered as it is, is super vulnerable to the president's popularity, but the senate has a very favorable GOP map this year. I think there are like 10 dems up for reelection in Trump states, or something crazy, but only a couple republicans in Clinton states. The president loses 10-20 house seats in midterms in a year when he's popular. Could be a bloodbath. Both houses should be in jeopardy given that the approval rating could be in the 20s by next fall. Already breaking records.
You're probably right. My only source of reasoning was that the Senate needs only lose one GOPer to a Democrat to flip.
