Joe Biden voted for the "Defense of Marriage Act", Yet many LGBT people supported him becoming president.

Obama opposed gay marriage as well. As did many prominent politicians, left and right.

The swing from opposing it to supporting it was a huge cultural shift, and I'm not sure I've seen anything like that happen so quickly, except maybe during a time of war. It went from being opposed by a strong majority to supported by a strong majority in... maybe 5-8 years? It was pretty impressive, and I think it's a sign that the marketplace of ideas can still function.

It helps a lot that it's really a harmless thing. It's giving people more freedom, not taking any away from anyone, and so as soon as it became clear that it wasn't causing a problem, everybody shrugged and went 'ok'.

Supporting one of two candidates in a first past the post election is simply supporting the lesser evil. There is no other information to glean.
