President Obama said Sunday that America still has a problem with powerful women—and that those struggles are the reason the country hasn’t yet elected a woman president. At a fundraiser for Democratic candidate Hillary Clinton, Obama said, “There’s a reason why we haven’t had a woman president... We as a society still grapple with what it means to see powerful women. And it still troubles us in a lot of ways, unfairly. And that expresses itself in all sorts of ways.” Obama said he’s disturbed by how tight the race is between Clinton and Republican challenger Donald Trump. “This should not be a close election, but it will be,” Obama said. “And the reason it will be is not because of Hillary’s flaws, but rather because, structurally, we've become a very polarized society,” he added.
