The ideal setup as far as helping the GOP look good is about 45 percent in the House, around 42 percent in the Senate, no more filibuster and a Democrat in the White House. This is enough Republicans for them to get some of the things they want - most revolving around money for the red states - and they'll be able to go out to their voters and brag about all the great things they did for them. Think about Lauren Boebert or MTG going back to their districts and speechifying about all the money, which they voted against, that's flowing to their districts. The things some of their people REALLY want - like an absolute abortion ban, a balanced federal budget amendment, elimination of Social Security or Medicare, and turning the US into a Christian nation - won't ever get done, which is a good thing.
If you put a Republican majority in either house or a Republican in the White House, nothing gets done. I don't remember which one it was that said this, but I remember a fairly prominent Republican member of Congress complaining earlier this year that Congress really hasn't done anything this term - and that's because the only two things the GOP can do are stonewall and delay. (Which are synonyms, but that's okay; they don't want to be known for having done only one thing.)
But you make the GOP a permanent minority party, let them help steer money to things they value while allowing Democrats to fund things we value, and QUIT FUCKING CUTTING TAXES so we don't have to keep increasing our borrowing, and the country will eventually thrive.
