Who Will Control the House? Updated Battleground Maps

By 270toWin Staff

July 13, 2018

There are just under four months until the 2018 midterm elections on November 6th. On this page, we present two battleground House maps based on the current ratings of Sabato's Crystal Ball, The Cook Political Report, and Inside Elections. 218 seats are needed to control the House in the 116th Congress that will be seated in January, 2019. 

Both maps are interactive - click/tap a map to use it as a starting point to create your own 2018 House forecast. 

Consensus Forecast: This first map is based on a calculated average rating of the three forecasters except that the darkest red/blue color is only used for those districts rated safe by all three forecasters. This gives us a broader view of the universe of seats that may be competitive on Election Day. Currently, 324 seats are seen as safe for the incumbent party, with 111 having various levels of competitiveness. Of those, about 90 are currently in GOP hands.

Most Competitive: This next map categorizes a district as competitive if at least one of the three forecasters gives it a rating of toss-up, tilt, or leans. It is a broader view of the more competitive races than one would get by looking at a single forecast. Absent a real wave election, these are the seats where control is likely to be won or lost. Republicans hold 58 of these 66 districts.
 
Note that the above narrative is as of July 13. As the forecasts evolve in the months ahead, the images in this article will update to reflect the then-current outlook.
