One of the dirty little secrets of the GOP establishment is that they don't like to be in the majority. It's much easier to complain about Democratic overreach in the minority and then do fundraising on things they will "fix" when they return to power.
If you don't believe me, then you should just notice that all the Republicans whining about the crisis on the Southern border under the Biden Administration were the same Republicans who kept blocking funding for President Trump's wall.
Trump exposed that old game.
