Here are the 2020 consensus ratings for Senate, House and Governor. At this time, they are based on the initial ratings of three forecasters: Sabato's Crystal Ball, The Cook Political Report and Inside Elections. We'll keep this map updated and likely add more projections as they become available.
Click any of the maps for the permanent URL, as well as an interactive version. Note that only races seen as safe by all three forecasters are given the darkest shade of red/blue on the map. This allows for the broadest look at the competitive landscape.
34 seats will be contested in 2020, including a special election in Arizona. 22 are held by the GOP, 12 by Democrats. To take control, Democrats will need to gain 3 or 4 seats.
As is the case every two years, all 435 seats will be up for election in 2020. Democrats currently hold 235 seats to 197 for the GOP. There are three vacancies; all were previously held by Republicans. If we assume those will stay in Republican hands*, that party will need to gain 18 seats to regain the control lost in the 2018 midterms.
Kentucky, Louisiana and Mississippi hold gubernatorial elections in 2019, with 11 more states to follow in 2020. Despite the deep-red lean of these states in presidential contests, all three races are seen as competitive, helped by the fact that they are taking place in an off-year. The country's governorships are roughly split between the two parties, with Republicans holding 27 of the 50.
* Two of these, NC-3 and PA-12, are safe GOP seats. NC-9 is much more of a toss-up. That seat has been vacant since the start of this Congress, as the November results here were not certified due to fraud allegations. A new election was recently ordered by the North Carolina Board of Elections. The Pennsylvania special election will be held on May 21; the North Carolina dates are not yet known.
