Campaign

The 2002 Montana elections got national attention when Baucus's opponent, state senator Mike Taylor, accused Baucus of having implied that Taylor was gay in a campaign ad. The ad was paid for by the Democratic Senatorial Campaign Committee, though designed by the Baucus campaign. The ad, which alleged that Taylor had embezzled funds from the cosmetology school he once owned, showed footage from the early 1980s of Taylor massaging another man's face while wearing a tight suit with an open shirt. Taylor dropped out of the race and Baucus won with 63 percent of the vote.
