One thing I happen to catch live (I never watch them, I only read the transcripts) is that “If you re-elect Obama I guarantee you will feel it”.
Now that I believe.
Early in the speech, Clinton said that something like “Obama is cool on the outside, but inside he burns for America”. More like, he wants American to burn.
He also said “look at his record” several times. I got the feeling that he doesn’t want Obama to win. That was Hillary’s first campaign speech for 2016.
