I believe you are wrong, EV---It is just 1+ year.
As I recall (and I'm REALLY tired right now so I might not be thinking correctly), I don't think it was Dasshole who just got re-elected. I think he was just helping to get Tim Johnson elected so the RATS could hold control and HE could remain as Senate Majority Leader.
I am almost certain Dasshole comes up for re-election in 2004.
According to http://www.congress.org/congressorg/bio/?id=535&submit.x=15&submit.y=9, Dasshole was first elected to the Senate in 1986, so he would have been re-elected in 1992, 1998, and hopefully (NOT!) in 2004.
