Pete Buttigieg probably isn’t really gay, and Elizabeth Warren may not be a woman — according to right-wing commentator Mark Steyn, guest-hosting The Rush Limbaugh Show.

Steyn, who also appears frequently on Fox News programs, was sitting in for Limbaugh Monday and talking about Sen. Cory Booker’s exit from the race for the Democratic presidential nomination. He critiqued the Democratic field for lack of diversity, saying Asian-American businessman Andrew Yang was the only person of color left in the contest (Steyn apparently forgot about former Massachusetts Gov. Deval Patrick, who is Black, although neither Patrick nor Yang will be in Tuesday night’s debate). Then he made his bizarre comments about Buttigieg and Warren.

“The great repository of diversity now is Elizabeth Warren! The first woman of color,” Steyn said, referring to Warren’s past claims of Native American ancestry. “We know she’s, what is she, 1/1,054th of color? Actually, do we know she’s a woman? I mean, who’s to say that’s not all a big scam too? And it’s just going to be a bunch of septuagenarian white guys up there, along with Mayor Pete. Do we, are we really sure he’s gay? I mean, he looks like some guy from the accountancy department. He doesn’t — that’s a very nongay look. I don’t know.”

Of course, he was ignoring the fact that Buttigieg, the former mayor of South Bend, Ind., is married to a man — and that there is a diversity of “looks” among gay men, and some of them are even accountants. As for Warren, a U.S. senator from Massachusetts, there’s no evidence that she’s not a woman. Another woman, Sen. Amy Klobuchar of Minnesota, will be in tonight’s debate as well.

“Anyway, the whole thing is the diversity of the Democrat primary has completely vanished now,” Steyn continued. “Cory Booker is out. I love it, it’s this, just like big extreme geezer showdown. It’s dancing with the coots. That’s basically what the Democrat primary has boiled down to.”

Well, while some Democrats are disappointed that the field has become less racially diverse, it should be pointed out that Republican elected officials are overwhelmingly white and male, and that Steyn’s appeal to ageism overlooks that Donald Trump is a septuagenarian white guy — he’ll be 73 at the time of the presidential election.
