They may clear just enough Congressional seats to be able to be sworn in for a majority. They will try to only have the presidential results and possibly some major Senatorial picks up in the air. It may not be a brilliant plan and anything could go wrong - but that is not going to stop them from trying. They would have to clear Democratic congressional seats while at the same time suppressing the Republicans. I do not think they are going to have enough votes no matter how much they stuff those ballot boxes, so they just may go for the nuclear option. It may also explain why the Kenyan and others are pushing to get rid of the filibuster in the Senate - they have something planned.
