I don't know if this has been commented on specifically to Tom Cotton, but it's kind of ridiculous for an Arkansas Senator to complain about RCV (and to essentially admit to being an easily confused moron in the process) because, though not ranked choice or instant run-off, Arkansas is a run-off primary election state.
In most cases in these Southern run-off states the acknowledged purpose was to prevent black people from getting elected. Has Tom Cotton ever called for Southern run off primaries to be eliminated?
Explain that last bit, Frank. How do run-offs stifle black candidates?
(That wasn't meant to be confrontational haha I'm genuinely curious.)
