Suppose you have the following results in an election:
Smith 40%
Jones 35%
Johnson 25%
Since nobody got over the threshold of 50%, then they look at the ballots of everyone who voted for Johnson, and whoever they marked as their second choice gets those votes transferred to that candidate. So if 2/3 of Johnson voters listed Jones as their second choice and 1/3 of Johnson voters listed Smith as their first choice, then you would have (rounding)
Smith 48%
Jones 52%
And Jones would be the winner.
This is how Democrats and RINOs could band together to defeat MAGA candidates. Imagine this scenario where Smith is MAGA, Jones is a Democrat, and Johnson is a RINO.
Correction: 1/3 of Johnson voters listed Smith as their SECOND choice
Thanks for explaining... And this is why democrats only push for this ‘system’ in select areas. Their polling would tell them where to push for it and where to use the standard system.
