Every time some ridiculous shit like this happens, I remember when Howard Dean yelled a little too loud and that invalidated his entire political career.
He went on to run the DNC on the platform of healthcare reform and was instrumental in getting Obama elected with a supermajority trifecta. And then he was fired and Lieberman got to kill the public option.
He offered too much to maintain cultural hegemony.
Been thinking this thought a lot lately. IIRC he was a decent man and likely would have been a decent president - but god forbid he get a little excited at a rally. Meanwhile, Trump has proven that literally nothing he could do or has done would change the mind of his voters. He could start and end every speech with a Howard Dean scream, and no one would even bat an eye.
(And I seem to also recall hearing that the isolated microphone of his scream that we've all heard a hundred times did not reflect how it even sounded at the event.)
