Most House districts voted along partisan lines — and the Democratic environment

Every House district’s FiveThirtyEight partisan lean by its 2018 vote margin

Partisan lean is the average difference between how a district votes and how the country votes overall, where 2016 presidential election results are weighted 50 percent, 2012 presidential election results are weighted 25 percent and results from elections for the state legislature are weighted 25 percent.

Only races with at least one Republican candidate and one Democrat are shown, and 2018 election results are unofficial as of Nov. 19.
