Read what I wrote. At no point did I say he should drop everything else and singlehandedly force through a law mandating gay marriage. First, that isn't possible. He's president elect, not Senate Majority Leader. What I said is that he could come out and say, in ONE SIMPLE SENTENCE that he would not, ever, under any circumstance, SIGN a passed bill that outlaws rights to certain individuals based on thier differences to others. In doing so, he will have spent all of about 8 seconds and could give the message that, 'try all you want to drive the wedge through America and deny more rights to more people, but that bill will stand ZERO chance of being signed into law as long as I am president of the United States.'
If his administration will collapse under the weight of one pro-active sentence, he should still be at the state legislature level.
