Animosity toward Joe Biden is at record highs among Republicans as they were among Democrats toward Donald Trump when he was in the White House.

Why are Americans so polarized? Will voters defect from their Democratic or Republican party affiliations to support "the other" presidential candidate or a candidate representing the Green Party or No Labels party?
