Krauthammer, referring to Obama's farewell speech, wrote "The final speech, amazingly, could have been given, nearly unedited, in 2008. "
I fear he suffers from narcolepsy, or he is yet another right-winger trying to gaslight us.
A few quotes from Obama's speech:
"If I had told you eight years ago that America would reverse a great recession, reboot our auto industry, and unleash the longest stretch of job creation in our history - if I had told you that we would open up a new chapter with the Cuban people, shut down Iran's nuclear weapons program without firing a shot, take out the mastermind of 9/11 — if I had told you that we would win marriage equality, and secure the right to health insurance for another 20 million of our fellow citizens — if I had told you all that, you might have said our sights were set a little too high. But that's what we did. That's what you did."
There's lots more.  Don't let Krauthammer gaslight you.
