Biden's five biggest fails of the first Presidential debate

98MM News host Gabriella Power has pointed out five of Joe Biden's most embarrassing blunders during the CNN presidential debate.

The 81-year-old President accidentally claimed America had a "thousand trillionaires" while speaking about tax law.Mr Biden corrected himself, "I mean billionaires".

Ms Power said it was "widely expected" that a "stronger than usual" Joe Biden would take to the stage after he spent a week "hiding" at Camp David.

She claimed Biden "failed" to get through the debate without making big "mistakes".

"If it somehow wasn't clear before, it is crystal clear now... Joe Biden is not cut out for the top job," Ms Power said.
