Trump and Biden in Trouble

A new poll shows Donald Trump and Joe Biden tied for the Democratic presidential nomination in 2024. John Avlon says it's a sign of things to come that both parties will have to change their candidates if they don't want to lose this race. He says Democrats are going to look at Trump's troubles and say, we don't need to change horses because there is a possibility that Trump can beat Biden.Avlon: We're locked in this extreme embrace of our politics which is just going to cause more damage to our society than anything else.
