Does it matter what drives someone to vote for a candidate if the outcome is all the same? It feels like we're discussing manslaughter vs. first degree murder. I don't want to be friends with someone who takes the life of someone else and doesn't feel remorse for it. Maybe it's a good theoretical exercise, but life is too short for me to appreciate the various reasons that might drive someone to become an asshole.
