We are now 35 days from the 2018 election. For most of 2018 there has been speculation about the Democrats taking the House. But until the last month the data on individual districts has been sparse, and predictions have been based on things like the generic ballot which is itself subject to significant error.
The table below lists the seats that will decide if the Democrats retake the House. It is based on the Democratic margin from 2016. If there is an incumbent running, his or her margin in 2016 is used, if not then Clinton’s margin is used. I have also included a running tally of the number of seats the Democrats would win if they won every seat in a particular group. For example if the Democrats every seat where the GOP margin was 7 points or less they would win 218 seats, exactly the number of seats needed for majority.
What the chart shows is just how protected the Republicans are as a result of gerrymandering.
