Pres. Biden came out swinging at his rally in Detroit on Friday, with a volley of zingers against Trump, self-deprecating jokes about his own age, a laundry list of his policy accomplishments and plans for a second term, and defiance against the punditry and members of his own party who doubts about his ability to stay in the race. Many came out to praise him. “the best performance he’s given since the State of the Union," "Joe Biden is knocking it out of the park at his Michigan rally," etc.
