Advocacy groups have launched unprecedented voter registration efforts aimed at the state’s small but rapidly growing Latino population. The nonprofit Henry works for earmarked $300,000 for outreach in Iowa shortly after Trump got into the race, and the group’s field workers have led Spanish-language caucus training sessions for voters in most of the 11 counties where Latinos constitute more than 10% of the vote.

Democratic and Republican campaigns have also been wooing Latinos angered by Trump’s rhetoric. When Jeb Bush’s Latino outreach workers field questions about Trump, they often tell voters that caucusing for Bush is the best bet to combat the real estate mogul.

Whether a similar movement takes shape across the country remains to be seen, but many Latino leaders are hoping Trump could be the catalyst to push their growing but chronically underperforming electorate to the polls. There is talk of a “Trump effect” rivaling Proposition 187, the anti-illegal-immigration measure that jolted California Latinos to action 20 years ago and is credited with helping create the state’s current Latino power structure.

“My gut is that it’ll be substantial,” Democratic consultant Bill Carrick said of Latino turnout in November. “They have been activated.”
