The republic parties have majority of seats in very house except senate?

The US the government is already formed and operating. The party that controls the government is based on who is sitting as the President and what party they represent. We have a checks and balance system, so if the President is not doing what the people want the congress has the ability to over ride his veto by a 2/3's majority. The lower house the house of Representatives start all funding bills, the senate which is the cooling plate has the ability to filibuster a bill which will defeat it without a actual vote taking place.
