From the Washington Post:
Bloomberg News columnist Margaret Carlson and I were stealing glances at each other when singer Melissa Etheridge asked New Mexico Gov. Bill Richardson an easy question: "Do you think homosexuality is a choice, or is it biological?" His response was quick: "It's a choice!" My visible reaction to Carlson was equally quick: "Oh, no, he didn't!" <snip> The forum's organizers hoped to get the candidates to show their concern for the gay and lesbian community and to see whether their understanding emanated from their consultant-generated talking points or from their hearts. Clearly, Richardson's head needed some work. Even his campaign recognized this -- it issued a "clarifying" statement not one hour after the event. And on a gay radio show the next day, Richardson told host Michelangelo Signorile that he didn't understand the question because of jet lag.
