The Las Vegas Sun has a great primer on what will take place at Nevada's caucuses Saturday.
First Read: "Frankly, the process is a bit of a joke: The caucus places start and stop at different times throughout the state."
The Atlantic: "Each county was allowed to set its own caucus procedures this year, leading to a divergent array of start times and rules across the state... The bizarre arrangement leaves the door open to all kinds of campaign hijinks. Party officials say attendees at the evening caucus will have to sign an affidavit swearing that they didn't already vote earlier, and their names will be checked against the voter rolls."
