“Though, in reviewing the incidents of my administration, I am unconscious of intentional error, I am nevertheless too sensible of my defects not to think it probable that I may have committed many errors. Whatever they may be, I fervently beseech the Almighty to avert or mitigate the evils to which they may tend.”

-- Pres. George Washington, Farewell Address, 1796

“It's one of the few regrets of my presidency — that the rancor and suspicion between the parties has gotten worse instead of better. I have no doubt a president with the gifts of Lincoln or Roosevelt might have better bridged the divide, and I guarantee I'll keep trying to be better so long as I hold this office.”

-- Pres. Barack Obama, State of the Union Address, 2016

“We are going to start winning again. We don't win anymore as a country. We don't win on trade. We don't win with the military. We can't beat ISIS. We don't win with anything. We are going to start winning again. And we're going to win so much, you are going to be so happy. We are going to make America so great again.”

-- Donald Trump, victory speech after winning the Republican New Hampshire primary Tuesday night
