He sought the Republican nomination for the United States Senate in 2002 and 2004, and the Republican nomination for Governor of Illinois in 2006. He was the Republican nominee for Illinois's 14th congressional district in a March 2008 special election and the November 2008 general election, losing on both occasions to Democrat Bill Foster. In 2012, Oberweis was first elected to the Illinois Senate in the 25th district. He again ran for the U.S. Senate in 2014, losing to Democratic incumbent Dick Durbin. In 2020, Oberweis ran for a third time in the 14th congressional district, this time losing to Democratic incumbent Lauren Underwood.
