Mayor Pete Buttigieg doesn’t believe he’ll be the first gay president if elected in 2020. “I would imagine we’ve probably had excellent presidents who were gay — we just didn’t know which ones,” he told “Axios on HBO.” “I mean, statistically, it’s almost certain.” Asked if he possibly knew which commander-in-chief was playing for the other team, the Democratic hopeful said: “My gaydar even doesn’t work that well in the present, let alone retroactively. But one can only assume that’s the case.”
