How the counting works
Every race you leave open is counted every possible way: two outcomes for most races, three in Montana. Eight open races make 256 combinations. Each combination counts once, so the percentages are shares of combinations, not odds. A 70% share doesn’t mean a 70% chance.
What counts as control
Democrats need 51 seats. Republicans need 50, because Vice President JD Vance breaks 50–50 ties. The 65 seats not on the ballot are 34 Democratic-caucus seats (including independents Angus King and Bernie Sanders) and 31 Republican seats. Independents who win this year only count toward a side if you assign their caucus.
Grading on election night
Locked maps are scored against projections from named news decision desks, as they appear on our results board. Maine and Alaska use ranked-choice voting, and Alaska’s tabulation runs Nov. 18, so some races may stay ungraded for days. Your map and lock time are saved in this browser only.
