STUART VARNEY: GAVIN NEWSOM'S CHINA TRIP SENDS A MESSAGE TO BIDEN: 'STEP ASIDE'

STUART VARNEY: Saturday morning, The New York Times releases a bombshell poll: Biden loses to Trump in five of six battleground states.

Obama himself has suddenly reappeared: is Michelle going to be the Democrats' savior?

The problem is that Democrats can't fire the president. They must persuade him to step aside. The pressure is intense. 

The New York Times: "Joe Biden is in trouble," The Wall Street Journal: "A five-alarm Biden re-election fire."
