Ouch. It’s going to be a long four months before Harris takes over if he wins.

‘Sleepy’ Joe Biden was caught napping twice during a rally in Michigan on Saturday, missing his cue to appear on stage and then forgetting his mask as he walked off it.

The 77-year-old was speaking at a rally in Flint alongside Barack Obama when he suffered the ‘senior moments’, just the latest in a series of gaffes that have dogged his presidential run.

The first came as Obama had just finished warming up for his old Vice President, and tried to welcome him to the stage by shouting: ‘My friend, the next President of the United State of America, Joe Biden!’

But Biden was nowhere to be seen, prompting Obama to shout for him again.

Eventually Biden emerged, jogging over to the stage from a nearby school building as Obama tried to get the crowd – who were confined to their cars as a Covid precaution – fired up, shouting: ‘Honk if you’re ready!’

During the rally itself, Biden also appeared to stumble over the word ‘healthcare’ while lining up a shot against the latest member of the Supreme Court – a Trump nominee – Amy Coney Barrett.

‘Donald Trump thinks health care is a privilege, Barack and I think it’s a right to have badakathcare,’ he said.

He fumbled again at the end of the rally, as Obama returned to the stage wearing a facemask and the two waved to the crowd before going off together.

Biden – who was wearing a mask as he emerged – appeared to forget he wasn’t wearing one as he departed.

Obama stopped him at the top of the stage steps and said a few words to him, after which he jogged back to the podium in search of the face covering.

After about 20 second of fumbling, Biden eventually found the face covering in his pocket and put it back in place.
