Unlike Romney, McGovern actually served.
The test for McGovern would have been whether he would have been willing to be a bomber pilot again against the North Koreans and ed Chinese. I am betting the answer would have been a resounding NO! In bombing Trieste, he was helping not only the noble American war effort but also helping relieve the Nazi pressure against his utterly ignoble cherished Stalinist USSR.
It is also true that no one in Romney's ancestry, nor the Mittwit nor the Mittwit's four sons have ever served in the military. Service in the military, as his late peer Leona Helmsley might have said, is "for the little people." Any aggressions can be taken out fox hunting or on the polo field or maybe some nice yachting regatta. Cracked crab, champagne, Chateau Lafitte Rothschild 1929 and such after a well-fought polo match sure beat K-Rations in the jungles of Southeast Asia or traveling the IED infested roads of Iraq or Afghanistan. As the Mittwit might ask: Can you believe the temperatures in Iraqi summer? Can't they just air-condition that country when they know our troops will otherwise be uncomfortable?
