Part of the problem is that people are sold on these guys as “Less Evil” every time. Clinton was the less-evil replacement for Bush. Bush Jr was the less-evil replacement for Clinton. Obama for Bush. Trump for Obama/Hillary. Biden for Trump. Maybe now Trump for Biden.
Evil is necessarily subjective, and a great deal of what we see as “evil” varies starkly based on where we’re getting our news and our values. What do you tell to the people who are doggedly convinced a mob of hispanic/arabic/chinese fentanyl fueled rape gangs are charging across the border to steal American children and murder them for their adrenochrome? What do you say to the folks doggedly convinced that the wrong President will bring about a thermo-nuclear holocaust or a dozen new 9/11s? How do you reason with a person who believes Plan B is no different than strangling a baby to death with your own two hands?
So much of the conversation about “Lesser Evil” is justifying a new and more brutal police state as a defensive measure against some horrifying phantom menace - be it J6 Groypers coming to lynch everyone to the left of Mitt Romney or Chinese TikTok dancers tricking American teenagers into perpetuating a Uyghur genocide.
When you’ve got Israeli Genocide versus Palestinian Islamic Jihad as your baseline for debate, there’s an endless capacity for evil even in the “Lesser” branch.
