The Democratic Party regained control of the House of Representatives in the 2018 midterm elections, with 35 House seats so far flipping from Republican to Democrat. As of now, Democrats will control 230 House seats compared to 198 for Republicans, with 7 races yet to be called or conceded.

FiveThirtyEight's deluxe House forecast — which includes everything from polls, district fundamentals, fundraising, and candidate quality — gave the Democrats a six in seven chance of taking back the House, predicting they would gain an average of 36 seats.

Their House model cast 14 contests as tossup, meaning both candidates had less than a 60% chance of winning, 15 as lean Democratic, and seven as lean Republican.

The results available so far show that 17 of these swing districts flipped from Republican to Democrat, six stayed in Republican hands, one flipped from Democrat to Republican, and four are still too close to call.
