So,here's what I read on the internet, and if you can't trust the internet, who can you trust?
They count the votes, come up with a fraction of total votes for each candidate, multiply by number of delegates, and that's how many each candidate gets. Except, what about fractions? If Joe gets 4.6 delegates and Amy gets 3.4 delegates, what then? Some of you might see an obvious answer, but that's not how they do things in Iowa. Instead, all fractional delegates are settled by coin flip, regardless of the size of the fractions.
