By Daily Mail Reporter PUBLISHED: 19:12 EST, 26 October 2012 | UPDATED: 19:45 EST, 26 October 2012 Praising George McGovern as a man who's 1972 presidential campaign inspired a new wave of political activism who's ramifications can still be seen today, hundreds turned out to pay respects Friday to the former senator they called the 'conscience for our nation.' Among the mourners attending Mcgovern's funeral in Sioux Falls, S.D.,  were three former Democratic presidential candidates: Walter Mondale, Gary Hart, and John Kerry. Like Mondale, each man spent time in the Senate before an unsuccessful run at the Oval Office.
