"McGovern is so far left that he is in danger of falling off the earth"

This quote by John G. Schmitz is a criticism of George McGovern, a previous United States Senator and Democratic presidential candidate. Schmitz is indicating that McGovern is too liberal and his views are so far left that they are beyond the world of truth. This quote is an example of hyperbole, as it is impossible for somebody to literally fall off the earth. It is most likely that Schmitz is trying to challenge McGovern's views by recommending that they are too severe and not grounded in reality. This quote is an example of the political polarization that has ended up being increasingly typical in the United States over the last few years.
