He looked shaky as he hobbled onstage Thursday night, but at the podium the drugs kicked in and Joe Biden delivered a commanding speech, by his standards. He handled an early bout of hoarseness like a pro, matched affect to content most of the way, and fumbled few words and none seriously.

Biden’s handlers had the otherwise inspiring setting of Philadelphia’s Independence Hall bathed in so much blood-red light, he looked like an opening act for Queensrÿche or Rammstein. Trying to create a setting for judgment and warning, they overshot the staging and made the white-haired ex-Senator look like a vampire sat up from a crypt.
