Former Michigan Gov. Jennifer Granholm woke up a relatively subdued crowd at the Democratic convention with an energetic speech that praised Hillary Clinton but also mocked Donald Trump's ego. One of the biggest applause lines came when she summoned a famous song: "Donald, you’re so vain, you probably think this speech is about you." The speech was, in fact, about him in parts, with Graham also taking issue with his "I alone can fix this" mentality. She reimagined the Constitution as written by him: "I the people, in order to form a more perfect union ..." Granholm is rumored to be in the running to be the next leader of the Democratic National Committee, notes ABC News. (More Jennifer Granholm stories.)
