I have little faith in the voting masses. I know too many who vote for someone they do not like because of their hate for someone else. Ranked choice is great for the well informed. But for the uninformed, easily manipulated masses it is simply a bit more complicated and I suspect they would vote against that option. So I guess the main reason for suggesting a "vote no" option is that I think it would be a positive change that more people might support, therefore making it more likely to accomplish. Ultimately the first issue is simply giving us more than two choices per position.
