Ranked-choice voting (and its Arrow equivalents) necessarily gives the worst outcome of any voting scheme, specifically it matches the least voting preferences[0][1]. Two-outcome FPTP on the other hand does not fall to Arrow’s impossibility theorem. This is the system most states in the USA effectively have. Intuitively, the least remarkable candidate will be elected because the opposing sides will reciprocally downgrade the candidates perceived as better. For instance Hitler was a result of an alternate voting scheme [2].
