Thomas McDermott Jr.

Following Pete Visclosky's decision not to seek reelection to the United States House of Representatives for Indiana's 1st congressional district in the 2020 election, McDermott declared his candidacy to succeed him.

In November 2019, McDermott publicly admitted that he had been fined $50,000 for improper campaign loans from his wife Lake Circuit Judge Marissa McDermott.

In 2015, complaints were dismissed by the Lake County, Indiana election board that McDermott allegedly violated finance laws for not properly itemizing over $200,000 in reimbursements for food, lodging, and rental cars.

In February 2014, McDermott agreed to the $200,000 settlement of a discrimination complaint filed by Hammond Housing Authority Director Maria Becerra. An editorial in The Times of Northwest Indiana later called for McDermott to make a public apology in the wake of Becerra's ouster from the Hammond Housing Authority.

On May 16, 2014, McDermott announced that he would step down as the chairman of the Lake County Democratic Party. It was speculated that McDermott planned on running for governor of Indiana in the 2016 election. On May 5, 2015, McDermott became the first mayor in Hammond's history to win four consecutive democratic primaries when he handily beat 6th District Councilman Homero "Chico" Hinojosa with 78% of the vote. On November 3, 2015, McDermott won the general election by a landslide margin of 87% to 13% over Republican Humberto Prado, a margin of 5,100 votes, becoming the longest-serving mayor in Hammond's history.

In 2011, McDermott won election for the third time, winning the Democratic primary with 68% of the vote and the general election in November with 80.2% of the vote in a rematch of his 2007 opponent George Janiec, a margin of 7,200 votes.

In November 2009, McDermott protested the arrest of his close associate David Woerpel, a postal worker, precinct captain and political commentator, after Indiana state police said they spotted marijuana growing in Woerpel's backyard. Charges of "possession of marijuana and maintaining a common nuisance" were later dropped and McDermott accused his political rival, Lake County Sheriff Rogelio "Roy" Dominguez, of "playing politics by targeting Woerpel." McDermott was mentioned as a potential candidate in the 2010 United States Senate election in Indiana to succeed the retiring Evan Bayh, but dropped out, and endorsed fellow candidate Brad Ellsworth.

On March 28, 2008, McDermott tacitly endorsed Senator Hillary Clinton for President and hosted a rally for the senator at the Hammond Civic center. McDermott later joined her campaign at a restaurant in Crown Point. Clinton's arrival in Hammond was the first visit of any presidential political candidate since Ronald Reagan visited Hammond (Hessville Park) in 1976, and Robert F. Kennedy in 1968. During the Democratic Presidential primaries in Indiana, McDermott was seen on CNN questioning Gary, Indiana mayor, Rudy Clay about votes that had not yet been posted many hours after the polls had closed. This "mayor fight" was satirized the following day on The Daily Show with Jon Stewart. He also criticized the busing of high school students to voting booths saying "These kids come from the worst performing schools in the state of Indiana and we are giving them a day off to go vote for Obama. They can vote on election day like everybody else."

McDermott led the charge to eliminate the Hammond Health Department in 2004, in 2005, and finally succeeding in September 2007. According to McDermott, this department was an example of duplicate government better left to the county to operate, while mayoral detractors claimed it was a valuable and much-needed service to the city, especially its poorest citizens. McDermott was re-elected in the 2007 mayoral race 52.4% – 47.6%, a margin of just 400 votes over Republican nominee George Janiec.

McDermott won the 2003 mayoral election for Hammond by defeating incumbent Republican mayor Duane Dedelow 52.1% – 47.9%, a margin of just 700 votes. During McDermott's first term in office, the dilapidated River Park Apartment complex was razed under the guidance of the Hammond Redevelopment Commission. Mayor McDermott's father, Tom McDermott Sr., helped attract Cabela's outdoor recreation retail store to the former Woodmar Country Club site in south Hammond in 2005. Critics at the time referred to the generous tax abatement awarded Cabela's as "corporate welfare" while supporters, including the mayor, cited a "public-private partnership."

McDermott's father, Thomas McDermott Sr., was a Republican who served as the 18th mayor of Hammond from 1984 through 1992. The young McDermott raised by his mother in Northern California's Napa Valley and spent summers with his father in Indiana.
