I don't think [pot] is more dangerous than alcohol.

I think I will still feel that same appreciation for what [Winston] Churchill and others have said is the worst form of government except all the alternatives.

My job is not to represent Washington to you, but to represent you to Washington.

Africa doesn't need strongmen, it needs strong institutions.

This kind of inequality - a level that we haven’t seen since the Great Depression - hurts us all. When middle-class families can no longer afford to buy the goods and services that businesses are selling...it drags down the entire economy from top to bottom. America was built on the idea of broad-based prosperity... That’s why a CEO like Henry Ford made it his mission to pay his workers enough so that they could buy the cars he made. It’s also why a recent study showed that countries with less inequality tend to have stronger and steadier economic growth over the long run.

There's a little perspiration involved in bringing about change too.
