Pete Buttigieg, the out gay mayor of South Bend, Indiana, visited The View today, answering the #1 question on people's minds now that he is a declared candidate for president:
What I think is that there are certainly people who would not vote for a gay man for president, but most of them probably wouldn't vote for many Democrats anyway. Some would, though, so I can see how his sexual orientation could be a small drag on the vote.
That said, he is a very diligent and serious candidate — unlike snake-oil saleswoman Marianne Williamson, GMAFB — and he could find himself being courted to be someone's VP. Perhaps for Kamala or Biden.
