Now that the dust has settled, we can make pretty good predictions of the outcomes even through 9 House seats, 1 Senate seat, and 2 Governorships haven't been officially called yet. The Blue tsunami was close to maximal within the realm of what was reasonably possible, although a handful of addition seats were close enough that they could have flipped with a one or two percentage point stronger blue shift.
It is looking like there will be 56 Democrats in the U.S. Senate (44 Republicans), and 260 Democrats in the U.S. House which is 59.8% (175 Republicans for a 85 seat excess of Democrats over Republicans when the most optimistic predictions pre-election had been about a 50 seat margin). These are not, however, supermajorities or even filibuster-proof majorities. But they do give the Democrats considerable room to pass party favored bills even with quite a few dissenters. Nine Senate seats were flipped by Democrats (and none by Republicans). Forty-nine house seats were flipped by Democrats and three were flipped by Republicans (one in Northern Maine, one in Texas, and one in Tennessee). 34 Senate Democrats and 31 Senate Republicans weren't up for re-election this year.
There will be 30 Democratic Governors, which is 60% (20 Republicans) (in addition, the District of Columbia's local government, which functions as a consolidated state and municipal government, is controlled by Democrats) that are home to about 75% of the U.S. population. Democrats flipped seven Governorships. Six Democratic Governors and eight Republican weren't up for re-election this year.
Democrats also made great gains in many state legislative races, and for other statewide offices, like state attorneys' general, state secretaries of state, state school boards, and state appellate court seats, in 2026. They gains trifectas in many states, gains supermajorities in Colorado and perhaps elsewhere, and broke GOP trifectas in many states. This slightly less up to date on federal and Governor race list summarizes some of these gains:
Democrats, on average, outperformed their 2024 results by about 13 percentage points, although the magnitude of this edge varied from race to race.
Partisan Politics In Puerto Rico
Puerto Rico, which holds Commonwealth elections only once every four years and did not hold one in 2026, by the way, is controlled by the center-right, pro-statehood New Progressive Party (PNP) has a trifecta with clean majorities in both houses of the Commonwealth legislature (19 seats in the Commonwealth Senate and 36 seats in the Commonwealth House), 37 municipal government majorities and 39% of the popular vote.
The main opposition party, the center-left, pro-commonwealth status Popular Democratic Party (PPN) has 34% of the popular vote, the non-voting Puerto Rico delegate to Congress, 5 Commonwealth Senate and 13 Commonwealth House seats, 41 municipal government majorities, and a minority of Puerto Rican Supreme Court seats including the Chief Justice. Some PNP members (including the Governor) are Republicans, and some are Democrats (which make up conservative and liberal factions within the centrist party). Member of the PPN generally favor the Democrats.
There are also three minor political parties.
The Democratic Socialist Puerto Rican Independence Party (PIP) with 6% of the popular vote two Commonwealth Senate and three Commonwealth House seats (but holds no municipal majorities).
The conservative Christian Democratic populist leaning Political Dignity (PD) formed in the year 2019, with 6% of the popular vote and one seat in the Commonwealth House and one in the Commonwealth Senate and a majority in one municipality's government.
The left wing progressive Movimiento Victoria Ciudadana (MVC) which holds about 12% of the popular vote, while advocating for a constitutional assembly and running on an anti-colonial platform, currently holds no elected offices in the Commonwealth government (having lost its seats in the 2024 election) and has no municipal government majorities.
There is also one unaffiliated independent in the Commonwealth Senate (who holds an "at large" seat). She is Eliezer Molina Pérez and was elected first in 2024. She has been the subject of an ethics complaint from a medium sized agricultural company, which seems to amount to a real estate and easement dispute. But, given the large PNP majority in the Commonwealth Senate, she is basically irrelevant politically.
