U.S. Congress
On May 16, 1986, incumbent Republican Congressman
George M. O'Brien withdrew as the Republican nominee in the 1986 election. The various precinct and township committeeman in
Illinois's 4th congressional district, a group which included Davis, nominated Davis to the vacancy. In the general election, Davis faced 28-year-old attorney/CPA and Democratic nominee Shawn Collins. Davis defeated Collins by a surprisingly narrow margin with 61,583 votes to Collins' 57,773 votes. Collins was able to win their shared home county of
Will and also win
Kane, while Davis won the portions of the district in
Cook and
Kendall counties. He served one term, 1987 to 1989. Davis voted against the
Abandoned Shipwrecks Act of 1987. The Act asserts United States title to certain abandoned shipwrecks located on or embedded in submerged lands under state jurisdiction, and transfers title to the respective state, thereby empowering states to manage these cultural and historical resources more efficiently, with the goal of preventing
treasure hunters and salvagers from damaging them. President
Ronald Reagan signed it into law on April 28, 1988. He was an unsuccessful candidate for reelection in 1988, losing to the
Democratic candidate,
George E. Sangmeister. ==After Congress==
