Following his victory in the Minnesota Democratic presidential  primary on June 3, 2008 which guaranteed his nomination, Barack Obama declared

The journey will be difficult. The road will be long. I face this challenge with profound humility, and knowledge of my own limitations. But I also face it with limitless faith in the capacity of the American people. Because if we are willing to work for it, and fight for it, and believe in it, then I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when the rise of the oceans began to slow and our planet began to heal; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on earth.

And now, nearly four and a half years later, as President Obama faces the many challenges with profound arrogance and cynicism and the country acknowledges his many limitations one might say that generations from now, we will be able to look back and tell our children that this was the moment when we' sadly couldn't provide good care for the sick because Obamacare limited access to the once excellent American health care system which rapidly deteriorated; unemployment remained higher than when Obama took office, and the jobless were lucky if they were able to get lousy jobs and thus many people have given up and simply dropped out of the work force; and this was the moment when we ended a war too early and endangered our nation and ruined our image as the last, best hope on earth."
