First, the Nevada GOP caucuses were closed to people not already registered as Republicans -- that means Trump won the subset of Latino voters who were already Republicans. What's more, according to the entrance polls, just 8% of the voters taking part in the GOP caucuses said they were Latinos.
The full sample size of voters captured by the polls was 1,573. That means Trump's claim that he is "No. 1 with Hispanics" is based on about 125 registered Republicans....

Should Trump become the Republican nominee, his current low standing among Hispanic voters could jeopardize the party’s hopes of winning the general election in November.

Ted Cruz and Ohio Gov. John Kasich.

But before the celebrity real estate mogul tries to beat Marco Rubio and Ted Cruz in their own Hispanic-heavy home states, a new poll out Thursday splashes some ice cold water on the narrative that “Latinos love Trump.”
A resounding 80 percent of Latinos nationwide have a negative opinion of Trump, according to a new Washington Post/Univision poll, putting him in dead last in terms of Latino support, trailing far behind all other presidential candidates.
