UPDATE: Incredible winning rate of Hillary Clinton's coin flips to break caucus ties, a fifty-fifty split would have had Sanders ahead
As about 12:21 AM CST, there had been six out of six coin flips that Clinton had won to break ties.
Counting the votes might be a little more complicated in Iowa. If each coin flip determines more than one of these 1,395 delegates, then Hillary would have had to win more than 50% of the coin flips to win the race.
UPDATE: The Washington Post reported that the Des Moines Register missed some cases.
The initial 6-for-6 report, from the Des Moines Register missed a few Sanders coin-toss wins. (There were a lot of coin tosses!) The ratio of Clinton to Sanders wins was closer to 50-50, which is what we'd expect. . . .There might have been a total of 13 coin flips with Hillary Clinton winning 7 of the six.
