Eight years ago, Hillary Clinton believed she needed to project an image of strength and experience to convince voters she could be the first woman president. The image, her strategist said at the time, was a kind of “tough single parent” rather than a “first mama.” But running for president in 2015, the Associated Press writes, Clinton’s gender isn’t something she seeks to explain or defend. The Democrat’s potential to make history as the country’s first female president has become one of her biggest applause lines.
