"Middle class" doesn't have to be precise or correct, because it's not a mathematical term. When a politician uses that term, they're doing it because they know that the guy making $20K (who doesn't want to identify with poverty), and the guy making $300K (who still feels a sting when he needs to buy a roof for his McMansion), and everyone in between considers themselves middle class. Hillary Clinton is just saying "I won't raise taxes for you, Friend."
