For those who say that the country won't vote for a gay guy (Pete), let's remember this: There are alot of people who won't vote for a pro-choice candidate. All the Dems are that. There is a lot of overlap in people who won't vote for a pro-choice candidate and people who won't vote for a gay guy. So, I don't think he really loses many votes over his sexual orientation.
I tend to agree with this. But, for whatever reason, Pete does very poorly (relative to others in the field) in head-to-head matchups with Trump. My guess is it has more to do with his age and ethos than his sexuality, but I don't know.
