I'd argue that the government is already broken apart and is in fact a cautionary tale of how doing so can lead to waste and paralyzed decision making. With the House having a Democratic majority, and the Senate and Presidency being Republican, no-one realistically expects anything is going to get done. Add to that mix the layers of state and local government before it gets to the road outside your house that's in need of paving... I think that government is broken up more than enough already.
