Input: Back in 2015  then  Vice President Joe Biden  appeared on The Late Show and host Stephen Colbert peppered  him  with questions about whether  he ’d run for president in 2016. However   Biden  was still reeling from the death of  his  son  Beau  and  Biden  said that  he  was unable to commit “110 per cent” to the task of running for president  despite the fact that Beau had urged  him  to continue to serve.  Biden  returned to The Late Show on Monday night and Colbert was ready for  him . “I’m not gonna ask ” said Colbert  before immediately asking  Biden  if  he  planned to run in 2020.
As for that whole 2020 question   Biden  wouldn’t answer other than to say that “the country’s never been more divided  we need a unifier.”
 He  also provided an update on  his  thoughts on President Donald Trump.
When  Biden  was on the show back in 2015   Biden  suggested that the American public give Trump a shot  before judging  him . “Have we given  him  enough of a shot at this point?” Colbert asked.  Biden  said  he  reached  his  tipping point with Trump after  his  “deafening” during the white nationalist rally in Charlottesville  Va.  where neo-Nazis were chanting “the same exact bile” against Jews that the Nazis used in the 1930s in Germany and a protester was killed by a white supremacist. Biden said there is now “a battle for the soul of this country ” and called for Americans to say “enough is enough.”
They also discussed the risks of “normalizing” Trump’s behavior. “What do you think has changed about the presidency with him being President?” asked Colbert. “How will this influence future presidencies?”  Biden  replied  “God willing  this will go down as the single exception in American history.”
When Colbert pressed him about who such a unifier could be   Biden  didn’t give any specifics  but he said there’s a whole new generation of Democrats entering politics who are ready to step up.
