The democrats lost eight Senate seats that year. In Virginia, Oliver North wouldHowever, there's a little more to that story. Let's hop in the time machine back to 1994 and look at the Republican win/loss record that year. For the seats Republicans gained, we have the following:
have won a seat if an independent candidate hadn't taken 11% of the vote. The fact that Kennedy still beat Romney in 1994, and by that much, shows how weak Romney is -- as does the fact that if Romney had run for re-election as Governor, he would have lost.
Arizona: Jon Kyl wins an open Senate seat (held by a retiring Democrat).Six of these eight wins occurred in open Senate seats. Santorum's win was over a not-very-established incumbent. So Bill Frist's win was the only Republican Senate victory in 1994 over an entrenched incumbent, and Tennessee was growing a lot more friendly to Republicans than Massachusetts.
Maine: Olympia Snowe wins an open Senate seat (held by a retiring Democrat).
Michigan: Spencer Abraham wins an open Senate seat (held by a retiring
Ohio: Mike DeWine wins an open Senate seat (held by a retiring Democrat).
Oklahoma: Jim Inhofe wins an open Senate seat (held by a retiring Democrat).
Pennsylvania: Rick Santorum wins over Harris Wofford, who was appointed
to the Senate seat in 1991 and won by less than ten points a special election to hold the seat in late 1991.
Tennessee (1): Bill Frist defeats a 3-term Democratic incumbent.
Tennessee (2): Fred Thompson wins an open Senate seat (Al Gore's seat, held
by a Democrat appointed to it but who chose not to run for it in 1994).
Every other Democratic incumbent was able to fend off his or her Republican challenger, even in more Republican-friendly states. These results suggest that incumbency can be a significant advantage in Senate races, even in wave years. They also suggest that Romney's defeat in 1994 is not exactly an outlier.
