If he came out and declared that he had a self destructive mental illness (that made him do your hypothetical), that got help and was cured and he is now engaged to a woman,
and his opposition was a lib who said that ‘marriage equality’ was a constitutional right and biblical and she wanted to give illegals the vote and ban my guns, and he was against all that,
it wouldn't be tough to choose between the two.
His having sex with a woman isnt as unnatural as if he had sex with a man.
That hardly made him a good candidate.
