Obama was genuinely qualified to be president. Trump was clearly unfit in 2016 (having never held elected office and run nearly all his businesses into the ground), and constitutionally disqualified after Jan 6 2021.

Trump was also reluctant to denounce or criticize white nationalists. He repeated and reposted neo-Nazi content and phrases. He is the one ordering a zealous yet haphazard dismantling of anything that breathes the words racial equity, and without a hint of pushback from his voters.
