Constitutionality of Ranked Choice Voting

[Skill and Chance]

Only John Roberts and the liberals believe ranked choice voting is constitutional under the current SCOTUS.

What are you basing that on?

How extreme the median justice is, who is much closer to Thomas than to Roberts.

What does that have to do with ranked choice voting, a subject which SCOTUS has never heard a case about?

Also note that Gorsuch and Thomas operate in super duper defer to the states mode on voting issues.  Gorsuch in particular is likely to be consistent on this.  While I think there is a reasonable equal protection argument against it, that argument would almost surely invalidate separate runoffs as well, and runoffs, especially in primaries, are a century+ longstanding tradition in many states.

What would the equal protection argument against runoffs be?

Not all votes counting equally and/or a candidate who finished on top in the first round losing the second round.
