I had forgotten this Lincoln quote. When told that his party would go down in defeat if they kept up with their platform and candidate a young Lincoln responded (20 years before he was President):
Address that argument to cowards and to knaves; with the free and the brave it will effect nothing. It may be true; if it must, let it. . . . The probability that we may fall in the struggle ought not to deter us from the support of a cause we believe to be just. . . . Let none falter, who thinks he is right, and we may succeed. But if after all, we shall fail, be it so.
I am not talking about the hard core left (who have their convictions) but of many opportunists and fools like Scott McClellan.
