Apparently each of these coin tosses resulted in a 2 delegate swing, from 4-4 to 5-3. So if Bernie had won just half the tosses, he would have won Iowa. Amazing.
I wonder if they used a plain old quarter or one of those commemorative DNC 50-cent pieces with Mao on one side and Lenin on the other? Both had massive foreheads so I'm not sure if the weight would have been off...
