Cary, NC

North Carolina allowed cities to experiment with IRV in the mid 2000's.  Cary, NC used IRV in 2007.  The Citydid a survery to see how well residents understood IRV.  The results were similar to what other research showed - If you were wealthy, college educated, and own a home, you understood how to vote.  Below is a copy of the survey results:

After trying IRV, Cary said "no more" and stopped using it.  One city councilmember said "I do not like instant runoff voting and have given my reasons why many times.  I'll take integrity in elections over funny math and 30% voter confusion any day."

Cary News - Opinion - IRV in Cary too risky:  "The Wake Board of Elections couldn’t follow simple IRV hand tabulation procedures. Ballots were mis-sorted, simple calculator mistakes were made and a non-public recount turned up missing votes."

Cary NC tries IRV, then says 'no more'.  "The Wake Board of Elections couldn’t follow simple IRV hand tabulation procedures. Ballots were mis-sorted, simple calculator mistakes were made and a non-public recount turned up missing votes."

Instant runoff voting poses problems: -  "IRV ballots are difficult to count. Officials had to manually tally the IRV results for an instant runoff election held in Cary as a pilot project last year. One small error cascaded into a miscount that had to be corrected at another date."
