Well, they didn't have to get sworn in to prove election fraud and throw them in prison. But again, that's not the game. Senate was the target. In other words anons don't need to be flipping out about the House because they have other plans for the House (show their true colors, do POTUS's bidding, continue to magically reveal how incredibly evil/stupid/against Americans they are, etc). It's circuitous to assume they "let Dems take the House" in order to arrest a bunch of them and let Republicans take the house right after that. What would be the point?
Long story short, we don't need the House for what's about to happen.
