The biggest clue to what was coming was the elevator packed with uniformed badged body amored Secret Service officers as we went up to the 9th floor for SNL last night. The came Secret Service hand held metal detectors at studio entrance. Even after that removal of all doubt, the surge of emotion at the audience 1st sight of Kamala #Harris was the most intense I’ve felt in that studio. (Yes, including when The Rolling Stones played.)
