by which senator Schumer won re-election in 2004 against little-known Republican challenger Howard Mills. The victory of a Democrat in the Senate election was not assured, because in recent decades the Republicans had won about half the elections for governor and senator. Lazio's bid was handicapped by the weak performance of George W. Bush in New York in the 2000 election, but it was also clear Hillary Clinton had made substantial inroads in upstate New York prior to Lazio's entry into the race. Exit polls also showed a large gender gap with Clinton running stronger than expected among moderate women and unaffiliated women. North Dakota Incumbent Dem-NPL U.S. senator Kent Conrad won re-election to a third term, over Republican Naval Reserve officer Duane Sand. Ohio Incumbent Republican Mike DeWine won re-election to a second term, beating Democrat Ted Celeste, real estate developer and brother of former Ohio Governor Dick Celeste.
