Why would you think that people who have the courage to act on their principles would regret it?
The amount of self determination it must take to smell the gasoline and still strike the match makes me think that the people who do this are capable of living with the consequences of their actions.
This makes absolutely no sense. Not inclined to rank candidates? What the fuck does that mean? Humans rank things. We have preferences. Malleable voters is also absolute nonsense.
Ranked choice favors the candidate that the majority of voters support. Republicans oppose it because they want to win seats where the majority of voters don't want their candidates or policies.
