One BIG difference is that McGovern flew over 25 bombing missions in Europe in WWII - one of the most dangerous assignments you could have. He was one brave, tough young man willing to give it all for his country. I may have disagreed with his politics but I respected the heck out of him and would have been proud to buy him a beer had I ever met him. Don’t even mention him in the same breath as that jug-eared wimp.
McGovern was an honorable and decent man. But one similarity between his campaign and Obama’s is that he had a running mate, Tom Eagleton, who spent time in a psych ward. Obama has one who should have been permanently committed years ago.
