In 1968 many more Americans turned against the war following the Tet Offensive, King was shot, and politicians began to get ready for the election for President in November. Many colleges were shut down by students, and people burned their draft cards at public rallies. A group of radical hippies called the Yippies, led by Abbie Hoffman and Jerry Rubin, led a huge protest during the 1968 Democratic Convention in Chicago, where they tried to run a pig called Pigasus as a candidate for President. The mayor responded by sending in riot police who beat people up in front of news cameras. The riot police even beat the cameramen, reporters, and other innocent people. This was shown on the news, and many programs and television stations began to feel more sympathetic to the hippies for a while. This made hippie lifestyle much more mainstream through the early seventies.
