Openly gay Wisconsin Representative Tammy Baldwin says she is considering a run to succeed Wisconsin Senator Herb Kohl, who announced on Friday he would not seek a fifth term in 2012.

According to the Gay & Lesbian Victory Fund blog Gay Politics, sources close to Baldwin say she is “very likely” to run for the seat.

Chuck Wolfe, president and CEO of the Victory Fund, a group devoted to promoting openly gay elected officials, said Baldwin's campaign would be a top priority for the group.

“This would obviously be a top priority for us. Tammy Baldwin has been an outstanding congresswoman, and she'd be an outstanding senator,” Wolfe said.

Baldwin is among the four openly gay lawmakers serving in the House. Also gay are David Cicilline of Rhode Island, Barney Frank of Massachusetts and Jared Polis of Colorado.

The 49-year-old Baldwin was first elected to represent the people of Wisconsin's 2nd congressional district in 1999. For 8 years prior she served in the Wisconsin Assembly.

“This would be a remarkable milestone for LGBT Americans,” Wolfe added. “Congresswoman Baldwin is one of the most admired officials I know. She would have the strong support of those who want to see our economy work for all Americans, and who believe that all voices deserve a place at the table.”

Baldwin is a perennial favorite among her constituents – she won 63% percent of the vote on November 2 – but remains untested in a statewide election.
