Democratic House candidates outperformed Clinton in the midterms
The voting patterns in Tuesday's House midterm elections shifted only slightly to the left of the 2016 election. But as this graphic shows, Democrats picked up 28 seats in districts that President Trump won in 2016 — and that's a big part of the reason they'll be in charge of the House next year.
How to read this chart: Democrats in the upper left won in districts that Trump carried in 2016; Republicans in the bottom right won in districts carried by Hillary Clinton. For races above the diagonal line, Democrats won by larger margins and Republicans won by smaller margins compared to the 2016 presidential vote. Candidates without challengers and those who won by margins greater than 50 points are excluded.
