The networks are saying that the U.S. House of Representatives will flip to the Republicans, but the Senate, in all likelihood, will stay with a Democratic majority.
If I recall my high school Civics class correctly, the House was supposed to reflect the passions of the American people, but the Senate was supposed to be largely immune from those passions. In this election, it looks like the House results are reflecting the passions, as the Framers intended. In many states, the House Democrats who voted in favor of broad expansions of federal governmental power and significant deficit spending are being wiped out. The message in favor of a smaller, less intrusive, less costly federal government seems clear.
In the Senate, the World’s Greatest Deliberative Body has not been quite as driven by those voter passions. New, conservative candidates like Rand Paul and Marco Rubio have won in some races, but in other states the voters have rejected some of the more fringe-oriented candidates — like Christine O’Donnell in Delaware. Of course, the design of the Constitution means that more than 60 of the Senate did not stand for election in this cycle. These current Senators will deal with the new members of the Senate but also will be thinking, hard, about what the political climate will be when they stand for reelection in two years, or four years.
The Constitution was carefully designed to have a bicameral legislature with houses with different interests and different perspectives. In this election, that careful design seems to have worked as intended.
