Yeah, Sanders is probably going to drop out sometime in the next two weeks.
I'm happy that there are some Clinton supporters here that can see that there was a shift in tone and even the message.
There was no shift in tone. The reporters who cover him say that he does it many times, not attacking Clinton in one speech and then a few hours later hitting her hard in the next one.
It's one more sign of his erratic campaign and character.
The peak of the speech was just "AND WE WILL... (simplistic talking point) (pause for applause) AND WE WILL..." on repeat. The first ten minutes was him telling his supporters how great they all were as they chanted "Bernie or Bust!!", and then the last two minutes was him basically saying "yeah, Hillary won California", letting his supporters boo her, and then promising to go to the convention and skedaddling. There was nothing diplomatic or certainly presidential about it. It was just his standard concession speech. Tell them it's their victory, give your stump speech, briefly acknowledge reality before promising to continue the fight in the next state and leave ASAP.
