The GOP can get Clinton on the stand for lying about cheating on his wife, but the liberals couldnt get Bush on the stand for passing a bill that helps only the drug companies, his connection with enron, or lying to the people about iraq, if they had the evidence right in front of them. Kinda funny huh?

It's called "control of Congress."

The party in charge of a given house of Congress controls that house's committees, and the committees control the investigations. If you don't have control, you can gripe all you want, but you don't have subpoena power and you don't have impeachment power.

Republicans control both houses of Congress. Hence the lack of interest in investigating a Republican president.

Another indictment of the two-party system, since it subverts the intent of the founders that Congress serve as a strong check on the executive, and vice versa.

That said, sometimes a Congresscritter bucks his party for the sake of personal belief. I can't remember the name right now, but there's a GOP senator currently holding hearings on intelligence issues, I believe, in conflict with the White House.

Another good argument for never allowing one party to hold the office of president and both houses of Congress. Thanks!
