The Nevada Democratic Party unveiled the “Caucus Express” this week. Any Democrats who pre-registers online can get details about their caucus location and can sign up for text-message updates.

The tool aims to guide voters on how to participate in a caucus, which is more time-consuming and unfamiliar than simply casting a ballot in a primary. It’s online at caucus.nvdems.com
