No, Pelosi is the most powerful person, Reid not so powerful. This power will and is only breeding more corruption. The sheep are being lead to the slaughter so to speak. ACORN will be the tool that ultimately bankrupts the U.S.
Ironsides, if there is corruption, Democrats will be voted out. That is usually the way, after a few years, corruption sets in.
Thus in 1994 there was plenty of corruption in the Democratic Party, they were defeated. Republicans came to power vowing to clean up Washington and quickly became part of the establishment. By 2006 they were up to their neck in corruption (Tom Delay, Senator Ted Stevens and several more). They were thrown out.
Give Democrats say, ten years on control of Congress and corruption will set in. Thus watch out for 2014 election, assuming Obama is reelected. Second midterms are usually a disaster for the governing party. In addition, corruption will have set in. I would say it is a near certainty that Republicans take control of the Congress in 2014 (assuming Obama is reelected).
The question is, can Republicans take control of the Congress before that. As of now that seems unlikely.
