Democrat Paul Kanjorski of Pennsylvania has lost a seat that had been in Democratic hands for 26 years. He was defeated by a Republican mayor, Lou Barletta of Hazelton, who gained national attention for get-tough policies on illegal immigrants.
Republicans have also captured three Senate seats that had been held by Democrats. And they're holding onto a Senate seat in Missouri. Republican Rep. Roy Blunt defeated Democrat Robin Carnahan in the battle for the seat that was held by the retiring Kit Bond.
Conservative Republican Mike Lee won Utah's Senate race. Incumbent Bob Bennett had been rejected by Republicans after Lee and others said he wasn't conservative enough.
