Male voters must break their sexist inclinations so the country can “get over the hump” and elect its first female president, President Obama said Tuesday.

In a message directed “to the guys out there” at a campaign rally at Capital University in Columbus, Ohio, Obama said, “[T]here’s a reason why we haven’t had a woman president before…”

“And we have to ask ourselves, as men — because I hope my daughters are going to be able to achieve anything they want to achieve — and I know that my wife is not just my equal but my superior,” he continued.

“I want every man out there who’s voting to kind of look inside yourself and ask yourself, if you’re having problems with this stuff, how much of it is that we’re just not used to it. So that, like, when a guy is ambitious and out in the public arena and working hard, well, that’s okay; but when a woman suddenly does it, suddenly you’re all like, well, why is she doing that?” he added.

Obama’s closing argument for his possible successor comes as GOP presidential nominee Donald Trump has a slight edge over Hillary Clinton in the Buckeye State.

The RealClearPolitics average of Ohio polls shows the mogul with a 2.5-percentage-point lead, with Trump getting 46.8 percent of the vote and Clinton 44.3 percent.
