If that were to happen it would be a walkover, and we're having Trump for another term. (Only a severe write-in campaign from the Dems on ONE person would have a chance to dethrone Mr. Incumbent)
It would but, the Democrats would justify it nonetheless. You know what happened in 2016. They picked Hillary Clinton then, Bernie Sanders folded like a lawn chair. No doubt rewarded somehow. Sanders supporters will not vote for Hillary Clinton or Joe Biden for the most part so, she is still getting the voters that are loyal and will vote for her. Joe Biden has more Democrat voters against him. BLM will not vote for him if he will not promise to defund the police. And if he defunds the police, more Democrats will not vote for him. Sanders supporters do not like him one bit and also, want their free tuition and free student loans to get their votes. Democrat Globalist power brokers see him as a weak link and would rather ditch him. They have been saying so, for months now.
