Richard Albert Professor of Law, Boston College :
Republicans are a long shot to win the House in 2010. But for the sake of good government, Americans should hope that Republicans somehow manage to win both the House and the Senate in 2010. That is the only way to ensure the integrity of the separation of powers, which is the cornerstone of the United States Constitution. Because when the same party controls Congress and the presidency, Congress bends almost blindly to the will of the President, legislative oversight of the executive diminishes in both quality and intensity, and power becomes concentrated in the presidency rather than dispersed, as it should be, between Congress and the President.
