Anxieties over Nevada caucuses mount following Iowa chaos

• Nevada was going to originally use the same app used in Iowa but has since scrapped those plans. Organizers told the AP that state party officials emphasized that the "Caucus Tool" is not an app, but did not explain how it was different.
• Compounding matters, Nevada will offer early voting in its multi-stage caucus process — which Iowa didn't attempt.

The big picture, via Axios' Stef Kight: Wyoming is the only other state that will hold a traditional caucus this year — on April 4.

• North Dakota also has a caucus, but it will be "firehouse style," allowing participants to cast ballots at certain locations over several hours.

The bottom line: Concerns over election security and confidence in electoral results have only grown since Russia interfered in the 2016 presidential election, as the AP writes, "Iowa’s problems demonstrated that it doesn’t take a foreign government to cause chaos."
