On fate and a deck of cards - Jennifer Medina in NYT:

"In most ways, the caucuses in Nevada work as they do in Iowa, and Democratic officials have emphasized the ease of the process: You show up at your local precinct, often a nearby school or community center, find the sign with your chosen candidate and wait a few minutes to hear whether your candidate is viable — caucus-speak for having at least 15 percent of all support in the precinct. (If there is a tie in the precinct, a deck of cards is used to break the tie; whichever campaign pulls the highest card, gets the delegate. Iowa relies on a coin-flip in case of a tie.)"

We all know that a lottery could replace our voting system and could work rather well, but a deck of cards might be the better solution.
I also like the idea that people (voters) get to hear whether their candidate is "viable" or not. Simply lovely, "don't vote for your candidate, Mr. X. is not viable."

Also beautiful to announce your divorce in this manner: "I love you, but I feel, and I discussed this with the children, that I'm not viable in this house anymore. My support is below 15%. So I quit the race."
