The 1998 run for the 6th District U.S. House seat was Tom Tancredo's first campaign for Congress. He defeated Democrat Henry Strauss with 55 percent of the vote.
He defeated Dem. Ken Toltz in the 2000 election with 54 percent of the vote. He was re-elected in 2002 with 67 percent of the vote.
In 2004, he announced that he would no longer honor a pledge he made when he was first elected to observe term limits, and would run for a fourth term. He ran unopposed in the 2004 GOP primary and faced Democrat Joanna Conti in the general election.
Tancredo served two terms in the Colorado Legislature from 1976 to 1980.
