Do US Senate election run-offs run ad infinitum?
Watching the events unfold from across the pond (I am a UK citizen) I am keen to learn the systems in place with the elections in the US.
I have seen that just like in the 2020 general election (Why are there run-off elections in Georgia this year?) there is to be a run-off election in this years US Senate election in Georgia.
How this came about is another question which I may ask later, but for this question I know what I am asking below are 3 questions on top of my main question, but they are interlinked as I am trying to understand how many run-off elections can be carried out.
- Do the 3 candidates who ran this year — Raphael Warnock (Democrat), Herschel Walker (Republican) and Chase Oliver (Libertarian) — run in the run-offs or is the run-off only run with the 2 candidates with the most votes (Raphael Warnock and Herschel Walker)?
- If all three are run again, what happens if there are similar results (nobody gaining at least 50% of the vote)? Does another run-off happen and keep happening with the 3 candidates until the 50% minimum is reached?
- If there are 2 candidates and the very unlikely occurs where both candidates get exactly 50% of the vote, is there another run-off?
