It is my great honor to serve on the Board of the Houston GLBT Political Caucus. I can, with the greatest of confidence, recommend their slate of endorsed candidates. The Caucus has one of the most rigorous screening processes of any organization I've ever been involved with. Ever candidate must submit a written questionnaire on LGBT issues and screen with a panel. The panel then makes a recommendation to the Caucus' membership which votes for endorsed candidates. It is a very open and accessible process and our membership subjects candidates to the highest of standards (which explains why their are some races for which no endorsement was made).
Don't forget, you can print off this endorsement slate and take it with you to the voting booth.
