“Trump is energizing Latinos, I suppose,” said Antonio Gonzalez, the president of the William C. Velasquez Institute, which bills itself as a nonpartisan public policy organization with a Latino focus.

“This is exactly what happened with Prop. 187. There were only two years where Latinos turned out for midterm elections at the same rate as in presidential elections. That was 1994 and 1998 — and those two elections are what transformed California from a purple state to a blue state.”

Alvarado, the GOP strategist, agreed, saying that “we’ve seen this before in California” with Proposition 187.
