You never fully get over [losing a presidential campaign]. But I've had a good life. I've enjoyed myself 90 percent of the time.

The earth has enough knowledge and resources to eradicate this ancient scourge. Hunger has plagued the world for thousands of years. But ending it is a greater moral imperative now than ever before, because for the first time humanity has the instruments at hand to defeat this cruel enemy at a very reasonable cost. We have the ability to provide food for all within the next three decades.

It is simply untrue that all our institutions are evil,... that all politicians are mere opportunists, that all aspects of university life are corrupt. Having discovered an illness, it's not terribly useful to prescribe death as a cure.

I flew a full string of 35 combat missions over some of the most heavily defended targets in Europe. We were hitting Hitler's oil refineries, his tank factories, his aircraft factories, his railway yards. Those were our prime targets.

Somehow politicians have become convinced that negative campaigning pays off in elections.

Never say anything that, down inside, you think is wrong.

I have a very deep concern about President Obama putting in another 21,000 troops into Afghanistan with the promise of more to come.
