Ranked Choice Voting

Monday, May 17 at 7:00 pm ET (New York)

In the 1992 presidential election, 43% of the popular vote went to Bill Clinton, another 38% to George Bush Sr., and the remaining 19% to Ross Perot.  More recently, in the 2016 Republican primary, 45% of the popular vote went to Donald Trump, 25% to Ted Cruz, 14% to John Kasich, 11% to Marco Rubio, and 5% to others.  Ranked Choice Voting (or "Instant Runoff Voting"), being tried in NYC for the first time in the upcoming election, aims to find an alternative method to mere "plurality" for choosing the winner of an election with many contestants.  Join Alex Kontorovich, MoMath’s Distinguished Visiting Professor, to explore the mathematical aspects of such systems, including various paradoxes and impossibility theorems!
