Openly gay Wisconsin state Representative Mark Pocan is considering a run for Congress.

According to The Capital Times, Pocan has been approached about running for Wisconsin Representative Tammy Baldwin's congressional seat, should she choose to seek another office.

Baldwin is among a handful of lawmakers considering a run to succeed Wisconsin Senator Herb Kohl, who announced last month that he would not seek a fifth term in 2012.

Sources close to Baldwin have said she is “very likely” to run for the seat.

The paper is reporting that the Gay & Lesbian Victory Fund, a group devoted to promoting openly gay elected officials, has inquired about Pocan's interest in vying for the seat.

Pocan said the group is “very enthusiastically” promoting his interest in Baldwin's seat.

“I am seriously considering a run for her congressional seat,” he told the paper. “But it's all in Tammy's hands. She starts the domino effect.”

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.

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.
