That is an alternative to first-past-the-post and delayed runoffs. One ranks the candidates by preference, and the ballots are counted by removing the candidate with the fewest highest preferences and then recounting with the preferences for that candidate being absent.
Let's look at this very simplified version:
4 people vote Cruz, Christie, Trump
3 people vote Christie, Cruz, Trump
3 people vote Trump, Cruz, Christie
2 people vote Trump, Christie, Cruz
The top-preference votes are Trump 5, Cruz 4, Christie 3. Under first-past-the-post rules, Trump would win, since he got the most votes. But let's see how it works under Instant Runoff Voting (IRV), a.k.a. Alternative Voting (AV).
Remove the candidate who got the least votes: Christie. The ballots become
7 people vote Cruz, Trump
5 people vote Trump, Cruz
So Cruz wins. This is because a majority of voters find Cruz OK even if not the best.

This was early this year. It had some interesting results.
Trump got 37% of the first choices, but only 10% of the second choices and 6% of the third choices. This decline slowly continued to about 2% or 3% until the last one, where it jumped up to 22%. So Republican voters either love him or hate him.
Ted Cruz won in second choices at 20% and Ben Carson in third choices at 16%.
The page also has an instant-runoff vote count on the poll. Here is who dropped out with how much of the vote at each stage:
0. Santorum 0.93%
1. Huckabee 2.39%
2. Fiorina 3.22%
3. Christie 3.53%
4. Kasich 4.05%
5. Paul 7.50%
6. Bush 8.66%
7. Carson 12.46%
8. Rubio 25.45%
9. Trump 49.32%
Winner: Cruz 50.68%
So Ted Cruz barely wins.

To address the plurality problem, we recently conducted a ranked choice poll in partnership with the College of William and Mary as well as Yougov, to demonstrate how ranking candidates provides voters with more meaningful choices and pollsters with more accurate information about the shape of the race. It allows us to simulate a national GOP primary using ranked choice voting (RCV). |
