The right saw that culture was trending against them, and instead of figuring out how to manage the shift, they turned to the nastiest, dumbest piece of crap candidate and ideology, because he bellowed loudly and promised to restore a lost past.
The right could have accepted gays. Instead they made anti-gayness a pillar of social conservative ideology.
But the price of that small victory, and 3 years of owning the libs, will be incalculably steep.
Bend with the times, or you'll break.
