Many people have stressed the historical importance of today's election so Jon Stewart decided to discuss Obama and McCain with an actual historian: the Pulitzer Prize winning Doris Kearns Goodwin. Goodwin discussed the negative political slogans of yesteryear, and remarked that McCain's smears are "No where near as dirty as the old campaigns." Apparently Jefferson's opponents claimed that if he won, rape and incest would be taught in schools. Not that Jefferson was so squeaky clean himself: he said John Adams was a "howling hermaphrodite." The worst was reserved for Grover Cleveland, who fathered an illegitimate child. According to Goodwin, people said, "women beware; he's going to have harlots at the White House." To which Jon replied, "Didn't Clinton run on that platform?" Clip above.Doris Kearns Goodwin Interview [The Daily Show]
