Illinois Senate career of Barack Obama

Main article: Illinois Senate career of Barack Obama
Obama was elected to the Illinois Senate in 1996, succeeding State Senator Alice Palmer as Senator from the 13th District, which then spanned Chicago South Side neighborhoods from Hyde Park-Kenwood south to South Shore and west to Chicago Lawn.[23] Once elected, Obama gained bipartisan support for legislation reforming ethics and health care laws.[24] He sponsored a law increasing tax credits for low-income workers, negotiated welfare reform, and promoted increased subsidies for childcare.[25] In 2001, as co-chairman of the bipartisan Joint Committee on Administrative Rules, Obama supported Republican Governor Ryan's payday loan regulations and predatory mortgage lending regulations aimed at averting home foreclosures,[26] and in 2003, Obama sponsored and led unanimous, bipartisan passage of legislation to monitor racial profiling by requiring police to record the race of drivers they detained and legislation making Illinois the first state to mandate videotaping of homicide interrogations.[25][27]
Obama was reelected to the Illinois Senate in 1998, and again in 2002.[28] In 2000, he lost a Democratic primary run for the U.S. House of Representatives to four-term incumbent Bobby Rush by a margin of two to one.[29][30]
In January 2003, Obama became chairman of the Illinois Senate's Health and Human Services Committee when Democrats, after a decade in the minority, regained a majority.[31] During his 2004 general election campaign for U.S. Senate, police representatives credited Obama for his active engagement with police organizations in enacting death penalty reforms.[32] Obama resigned from the Illinois Senate in November 2004 following his election to the US Senate.[33]
