The Election and Investigatory Powers of Congress

"If the Democrats take control of the House from the Republicans, the most important change will not be that Nancy Pelosi becomes House Speaker, but that the leadership of House committees will shift -- and even more significant, that there will be upheaval of committee staffs. Republicans will shift to minority staff positions -- and have to let go of a lot of staffers -- while the Democrats will get to hire a lot of new ones. These staffers serve two functions. The first is preparing legislation, the second is managing investigations. Given the likelihood of political gridlock, there will be precious little opportunity for legislation to be signed into law during the next two years -- but there likely will be ample opportunity and motivation for congressional investigations.

Should the Democrats use this power to their advantage, there will be long-term implications for both the next presidential election and foreign policy options in the interim."
