Georgia holds general election run-offs (except for president) if no one gets 50% of the vote. Two bills to change that have failed to advance, and it is now too late for them to pass. HB 419 would have provided that anyone who gets 45% is elected. SR 211 would have created a joint legislative committee to study run-offs.
Runoffs are better than plurality voting.
Ranked choice voting and approval voting are even better; they resolve the election without a second physical vote.
Plurality voting is the best system.
