Georgia's primary was a mess - but they narrowly avoided a runoff! If they hadn't, voters would've needed to go back to the poll a second time. Would voters go through that hassle?

If they had #RankedChoiceVoting, also called #InstantRunoffVoting, this would not be a concern. It's equivalent to a normal runoff election, but without the second/third/fourth time at the ballot box.
