There's no question that it's a little goofy that anything like this is determined by coin flip. But it doesn't actually mean anything - the flips were for the state convention, not the actual convention, and in the end Hillary and Sanders will almost certainly split Iowa's 44 delegates right down the middle.
What are the odds of winning 6 out of 6?
I'll bet the old crook is sad she didn't play the Powerball a couple of weeks back, her odds of winning that were better.
1/64. Not that far odds - about the same as getting three-of-a-kind in a game of 5-card stud.
