While I do think ranked choice voting would be better than our current system let’s not forget that it does have a pretty major downside. It can lead to someone nobody likes getting elected just due to how the system works. Veritasium (I think it was him?) made a video about different voting methods and all their downsides.

Basically math geniuses have been trying to find a solution to this problem since the dawn of time and so far all voting methods have inherent downsides.
