Biden goes into debate against Trump with set of challenges that he must overcome to sell voters on re-electing him

According to Donald Trump, Joe Biden is either a very accomplished or utterly incompetent debater.

When details of the presidential debate, which takes place in Atlanta on Thursday, were announced last month, Trump mocked Biden as “the WORST debater I have ever faced”, adding: “He can’t put two sentences together.” And yet, while speaking to the All-In podcast last week, Trump commended Biden’s showing in the 2012 vice-presidential debate.
