Bill Radke speaks with University of Washington historian Margaret O'Mara about mud slinging and crudeness in American politics.
After Donald Trump defended the size of his penis during a Republican primary debate, some people asked, have we hit a new low? According to O'Mara, the answer is no. Things like this have been happening for centuries.
And often, the vulgarity is a smoke screen that distracts from the real issues, O'Mara said.
