“Hamilton doubted the cohesive force of the Constitution to make a nation. He was so far right, for no constitution can make a nation. That is a growth, and the vigor and intensity of our national growth transcended our own suspicions. It was typified by our material progress. General Hamilton died in 1804. In 1812, during the last war with England, the largest gun used was a thirty-six pounder. In the war just ended it was a two-thousand pounder. The largest gun then weighed two thousand pounds. The largest shot now weighs two thousand pounds. Twenty years after Hamilton died the traveler toiled painfully from the Hudson to Niagara on canal-boats and in wagons, and thence on horseback to Kentucky. Now he whirls from the Hudson to the Mississippi upon thousands of miles of various railroads, the profits of which would pay the interest of the national debt. So by a myriad influences, as subtle as the forces of the air and earth about a growing tree, has our nationality grown and strengthened, striking its roots to the centre and defying the tempest. Could the musing statesman who feared that Virginia or New York or Carolina or Massachusetts might rend the Union have heard the voice of sixty years later, it would have said to him, 'The babe you held in your arms has grown to be a man, who walks and runs and leaps and works and defends himself. I am no more a vapor, I am condensed. I am no more a germ, I am a life. I am no more a confederation, I am a nation.”

Context: This may be the year when we finally come face to face with ourselves; finally just lay back and say it — that we are really just a nation of 220 million used car salesmen with all the money we need to buy guns, and no qualms at all about killing anybody else in the world who tries to make us uncomfortable.
Context: If the current polls are reliable... Nixon will be re-elected by a huge majority of Americans who feel he is not only more honest and more trustworthy than George McGovern, but also more likely to end the war in Vietnam. The polls also indicate that Nixon will get a comfortable majority of the Youth Vote. And that he might carry all fifty states... This may be the year when we finally come face to face with ourselves; finally just lay back and say it — that we are really just a nation of 220 million used car salesmen with all the money we need to buy guns, and no qualms at all about killing anybody else in the world who tries to make us uncomfortable. The tragedy of all this is that George McGovern, for all his mistakes... understands what a fantastic monument to all the best instincts of the human race this country might have been, if we could have kept it out of the hands of greedy little hustlers like Richard Nixon. McGovern made some stupid mistakes, but in context they seem almost frivolous compared to the things Richard Nixon does every day of his life, on purpose... Jesus! Where will it end? How low do you have to stoop in this country to be President?
