There's no party that has anybody elected to Congress (or to a state Congress afaik either, though there I may be missing one or two persons) that wants to even reduce substantially, let alone destroy, government. TBH, let's not be cute and drop "substantially". No major party wants to reduce the government at all. Didn't for a long while. The only disagreement is about how fast the government will be growing and who gets the benefits of the wealth transfers that would follow from that and who gets to control these trillions and get the goodies that come from controlling trillions of other people's money. There are disagreements on other subjects, but on the subject of Big Government the consensus is clear and present. No agency ever gets reduced power (or, the horror, disbanded!) whatever party is in power, the worst could happen is that one party's functionary would temporarily disrupt the implementation of other party's schemes.
