I'm no Hillary fan, but I do have some sympathy for any woman trying to win the US presidency. The deck is severely stacked against any woman becoming U.S. president. U.S. politics seems to demand an excessively masculine, aggressive presence at president. The media seems to think that if the candidate isn't some bomb-happy swaggering bully that they are unelectable. Paul actually gets hit by this same bias to some extent.
If any woman tries to play this swaggering bully game, they just get perceived as a bitch. It just doesn't work for women.
