In an experiment to test the new instant-runoff voting (IRV), the DFL held an extremely unofficial election in Minneapolis Tuesday among 13 potential DFL candidates for guv in 2010. The turnout of around 300 was so small that it may not be worth mentioning, but for the politically obsessed:

House Speaker Margaret Anderson Kelliher got the most votes, both on the original ballot and after they had been used to assign the ballots of the lower finishers to the higher finishers. The final IRV adjusted totals were:

• Kelliher: 55 percent
• R.T. Rybak: 45 percent

On the first round, state Sen. John Marty came in third with 12 percent; state Rep. Paul Thissen came in fourth with 10 percent and everyone else finished in single digits, percentage wise.

The results should be taken with pounds of salt. There was no serious campaign. Turnout was tiny. There were only three polling places, all in Minneapolis, although no proof of Minneapolis residency was required. Sure enough, two Minneapolitans came out on top.

While other cities, including St. Paul, had actual official primaries yesterday, Minneapolis didn’t have to, because it is using instant-runoff voting (also known as ranked-choice-voting) this year, which makes a primary unnecessary.

The full results are here.
