Hillary Clinton may have a Millennial problem on her hands. A survey from USA Today and Rock the Vote released last week found her main Democratic opponent, Vermont independent senator Bernie Sanders, is winning Democratic primary voters between the ages of 18 and 34 by more than 10 points, 46 percent to 35 percent.

That’s just some of the latest news to suggest Clinton has a greater challenge winning the Democratic nomination than previously thought. But if the former secretary of state can get through her primary, there’s reason to believe she won’t have an easier time with Millennials in the general election.
