In 1996, Weinzapfel ran for the United States House of Representatives in the 8th District of Indiana. He was defeated in a close race by one-term incumbent John Hostettler after narrowly defeating State Representative Rick McConnell of Princeton, Indiana. In the primary, Weinzapfel carried the more liberal parts of Monroe and Vanderburgh Counties, while McConnell won more conservative parts of the 8th District. Weinzapfel went on to serve five years in the Indiana House of Representatives for District 76. In this capacity he served as the Chairman of the Courts and Criminal Code Committee, the Environmental Affairs Committee and the Environmental Quality Service Council. In 2000, he served as attorney for Bowers Harrison LLP. Weinzapfel also served on the Financial Institutions, the Judiciary, and the Public Health committees. His accomplishments include helping to found the Southwestern IndianaRegional Development Commission. He served as the first president of the group. The commission is representative of Gibson, Posey, Vanderburgh, and Warrick counties in order to promote economic development and improve the quality of life in southern Indiana.
Mayor of Evansville
His first term as Evansville mayor began on January 1, 2004. In office, Weinzapfel focused on creating jobs and revitalizing downtown, primarily through the successful construction of the Ford Center, a multi-use indoor arena in with a maximum seating capacity of 11,000. He also started the Evansville Education Roundtable to provide a community-wide dialogue on improving education and has built a collaborative style of decision-making through his "Traveling City Hall" program. In the 2008 presidential campaign, he endorsed Barack Obama. During his last year as mayor, he oversaw an implementation of an overhaul of the city's accounting information system. An audit of his last year as mayor revealed significant problems with that implementation and the auditors issued a Disclaimer of Opinion. Due to his popularity in a politically competitive part of the state, there was some speculation of Weinzapfel running for governor in 2008 against incumbent Mitch Daniels and in 2012 when it was an open seat. He did not, however, enter either race. Weinzapfel joined Faegre Baker Daniels LLP as attorney in 2012 and resigned in 2014. There was also speculation that he may run for governor again in 2016; however, he did not. In 2014, Weinzapfel was selected as chancellor of Ivy Tech Community College Southwest as part of the college's organizational restructure. He served in that position through November 2019, when he left to join the Evansville law firm, Jones Wallace LLC.
On December 10, 2019, Weinzapfel announced his intention to run for Indiana Attorney General in the 2020 election against incumbent RepublicanCurtis Hill. On June 13, 2020, during the virtual state convention, delegates formally nominated Weinzapfel to be the Democratic nominee for attorney general, defeating his only primary opponent, state senatorKaren Tallian. The final vote tally was 1,057 votes to Weinzapfel and 1,009 votes to Tallian, a 48-vote margin out of 2,066 votes cast.
