Democrats had a trifecta but couldn't get DC and Puerto Rico statehood or voter right protections because of Blue Dog members of the party. They lost a critical election that led to some of the worst gerrymandered maps against them while most of their own gerrymandering attempts were overturned. Republicans now control the senate, house, judicial, and executive branch and can cement their power forever.

If you don't believe me just look at Mississippi. A state where demographics alone should've made it between blue and purple. Instead, 15% of all Black adults in that state are not allowed to vote. Similarly, in Florida, 10% of all adults cannot vote. Voters passed an initiative by direct democracy to allow felons to vote, but DeSantis just blocked it anyways and the courts, which he controls, backed him.

Democrats, despite winning the popular vote in all but 2 elections since 1988, are pretty much completely out of power
