Democratic hopes of retaining the Senate may end up resting on races like the one in Wisconsin, where Sen. Herb Kohl (D-Wis.) is retiring. If Rep. Tammy Baldwin (D-Wis.) is the Democratic nominee, she could face a tough race, especially if the Republicans run former Gov. Tommy Thompson.

Baldwin, who would be the first openly gay member of the Senate if elected, will be raising money in Los Angeles on Sunday, at a $1,000-per-person cocktail reception at the home of retired TV executive Blake Byrne, who chairs along with producer Bruce Cohen and his husband, Gabe Catone. The hosts include Rich Ross and Adam Sanderson, and attorney Loren Ostrow and Brian Newkirk.

A word of warning to all who attend: The home of Byrne, a major patron of the Museum of Contemporary Art in Los Angeles, is like a gallery in and of itself, and it’s a tradition of guests to take off their shoes so as not to leave scuff marks on the beautiful hardwood floors.
