I’m going to answer your question as if you are being serious and are genuinely curious.

• House Gerrymandering. Over the last few years - the GOP has gotten rid of multiple D-leaning house seats in Florida, Wisconsin, Texas and North Carolina (they tried in Alabama too). Even with that, they are just barely going to win the house on what should have been a decent election year for them.
• Senate - 2018 was a bad year for the GOP and a good year for the Dems. Due to that, them Dems picked up some seats that are less likely (Montana, Ohio, Ruby Red WV). This cycle, there are multiple states that picked an R president but a D senate member, albeit by smallish margins. This time around, the winds were more in the R favor, so Rs recouped those redder states, but didn’t so much in the purple states. The exception is Pennsylvania, which often elects one Senator from each party.

Heads up - 2026 Purple NC is also one of those states that often elects a senator from each party, so expect lots of ads during the race there. The beatings will continue until the color improves.

Double heads up - 2030 will be 2 years after the president who is elected after Trump (if that remains a thing). I’d say there’s a decent chance that the president will be a Dem unless someone can capture the same energy that DT rouses in certain demographics. That election cycle is usually one where the party in power gets trounced (though there are some exceptions), it also happens to be the year that the census occurs and redistricting takes place thereafter. The Rs won that fight last time. Following the trajectory I outlined, it’s likely the R’s will win it, again.
