U.S. Rep. Tammy Baldwin opened her senate campaign headquarters in downtown Milwaukee on Monday night.

The Madison lawmaker is the only Democrat in the race to replace retiring sen. Herb Kohl.

United States Senate hopeful Elizabeth Warren in a Dec. 15 blog post on Blue Mass Group announced her support of LGBT rights, including legalized same-sex marriage, anti-discrimination legislation, and programs that combat bullying.

“I’ve had the chance to say it in living rooms and school auditoriums, but I’m glad to have the chance to say it here,” Warren wrote. “No one — no one — should be discriminated against because of race, color, national origin, sex, disability, sexual orientation, gender identity or expression, or religion.”
