Unlikely story I know. It would be so foolish for him to have written that knowing anyone could view it. His history on gay rights are chequered for sure, but I believed him on that one.
To be fair to him, his voting stance on gay rights is clear. He's always voted in support. So what his personal belives are, has not affected his voting.
