But that rule expires at the end of this session of Congress.
When the new session begins, the Senators will enact a new set of rules governing the conduct of it's business. These rules will be adopted by a simple majority. We have at least 55 Republican Senators. There is no reason to enact a new 60% rule that will let the Democrats block all of President Bush's nominees.
Let your Senators know that if they vote for a 60% rule that you will no longer be silent when they try to blame their failure to get nominees confirmed on the 60% rule.
I was under the impression that, unlike the House, the Senate views itself as a continuing body (since no more than about 15% of it's membership generally changes from election to election) and doesn't regard it's rules as needing to be re-voted at the beginning of each Congressional session.
But I'm not an expert in this matter; I could be wrong. If you have better information than I, I'd appreciate hearing it.
