After one of the most expensive senate races in the history of Wisconsin, Democratic Representative Tammy Baldwin defeated former governor Tommy Thompson to become the first openly gay Senator in U.S. history.
Reuters reports the candidates raised at least $65 million in the fight to assume the seat of Democrat Herb Kohl, who is retiring after four terms in the Senate.
Baldwin's sexual orientation was never a main issue in the campaign. However, she was criticized by Thompson for her support of Barack Obama's health care plan.
Another openly gay politician, Democrat Mark Pocan, is expected to replace Baldwin in the House.
Baldwin spoke at the Democratic National Convention and campaigned for Obama in the days leading up to the 2012 election.
