7 8 10 4 first A B C A second B C A C third C A B B
B has the least first place votes and is ranked third. The instant-runoff is
7 8 10 4 first A C C A second C A A CC wins with 18 first place votes, A is second.
Now suppose that the 4 voters find out that C will win (``everyone likes a winner'') and change their vote for C to first place:
7 8 10 4 first A B C C second B C A A third C A B BA is ranked third with 7 first place votes. The instant-runoff is
7 8 10 4 first B B C C second C C B Band B wins with 15 first place votes and C is second!
