All Senators belong to congress not all Congresspersons are senators. Nobody doubts that the last three months of the Clinton presidency was a political firestorm, but during that time some things did get accomplished. I believe the implication was that though we all recognize that Bush us against the treaty, we must also recognize that there is a possibility that it was also not a high priority for Clinton. I'm not saying it is so...I'm just saying its possible. Below is some information on U.S. treaty ratification. I looked it up because I didn't know and it seemed readily accessible. Interesting info on executive agreements as well.

The legislative branch of the government is made up of the United States Congress. Congress is divided into two legislative houses: the House of Representatives, in which representation is apportioned according to state population; and the Senate, in which each state has two representatives. A person must be 25 years old to serve in the House. Senators must be 30 years old. Congresspersons must be citizens of the United States and must reside in the district (House) or state (Senate) they represent.

Negotiation of treaties. Again, the president is empowered to negotiate treaties. No treaty can go into effect, however, until it is approved by two-thirds of the Senate.

The president visits leaders of other countries to negotiate treaties and other important issues. Such negotiations are often subject to congres- sional approval; however, Congress traditionally allows the president a great deal of independence in conducting foreign affairs. Furthermore, the president can arrive at executive agreements with foreign nations, which do not require Congressional approval but which have the same force as a treaty .
