The caucuses in Nevada only have Trump on the ballot. He is "undemocratic" but not illegal, experts say.

“I can't help it that in Nevada the vast majority of Republicans work and vote for Donald Trump and not Nikki Haley,” Chris LaCivita, Trump's senior campaign adviser, told The New York Times. Many Republican in Nevada did not understand what was happening during this Tuesday's primary. By noon, only 30 people had voted in the primary.
