When did Democrats get so messed up about the sexes?

The latest, of course, is top Kamala Harris surrogate Mark Cuban’s boorish comment on “The View”: “Donald Trump, you never see him around strong, intelligent women. Ever.”

Apparently, the likes of Tulsi Gabbard, Alina Habba, Nikki Haley, Kellyanne Conway, and Melania Trump are invisible in Cuban’s eyes.

Not to mention Sarah Huckabee Sanders: We’re pretty sure she could chew Cuban up and spit him out faster than Joe Biden can demean half the country.

Nor the female execs Trump was promoting and relying on back in his real-estate prime in the 1980s.

Top Democrats simply believe as a matter of faith that the other side is sexist.

And they really have no clue how the other half lives: Witness the Harris campaign’s prolonged effort to let women know “your vote is a secret,” targeted at what the brain-trust clearly believes is a vast number of wives whose husbands bully them into voting Republican.

(They actually wasted Julia Roberts on an ad on this: beyond dumb.)

It’s a big country; we expect there is a case or three of such couples — but it’s also the 21st century, and the reasons married women have leaned Republican for the last half-century have a lot more to do with their “lived experience,” as the lefties like to put it, than with what their menfolk may think.

This one counts as a serious insult to the overwhelming majority of married women, however either half of the couple votes: an unintended insult, sure, but yet another sign that the Democratic elite doesn’t have a clue about the voters it needs to win over — and instead is the captive of truly dim stereotypes.

That goes double for the beyond-cringe ad from “Creatives for Harris,”  which featured a pack of actors playing a series of Village-People-stereotypical macho men proclaiming themselves “man enough” to vote for a woman.

Again, this is Harris fans imagining what the problem is, rather than realizing that a campaign that’s nonstop about symbolic abortion rights and Trump-is-a-fascist doesn’t give most men any reason to take her seriously.

As CNN’s Scott Jennings put it, “A lot of men think Democrats care more about dudes who want to become women than dudes who just want to be dudes.”

More: “No hunting, cosplay or cringy videos are going to change that. The bed is made.”

Maybe worse are the laughable efforts to paint Harris hubby Doug Emhoff and running mate Tim Walz as embodiments of some “new masculinity.”

(They wasted AOC, with all her undoubted smarts and charisma, on trying to put a shine on Dougie.)

And it all began with “White Dudes for Harris,” a Hollywood-dominated struggle session so conflicted that they just had to go for “dudes” instead of “men”: No man, woman or child in America needed to hear Josh Groban confront his white, male privilege.

Maybe before the next election starts, Democrats can work out their sexual issues — or at least learn to stop sharing them everywhere.
