This isn’t hard to understand. A huge proportion of Americans who identify *ethnically* as Latino also identify *racially* as white and white people tend to vote Republican.
Here’s an example of how race structures the politics of Latinx voters. Lighter-skinned Latinx voters are much less likely to vote Democrat. Moving from darkest to lightest skin, the likelihood a Latinx voter voted Obama in 2012 drops from 97% to 43%. rubenson.org/wp-content/upl… 
In that study, 78% of the lightest skinned Latinx voters identified *racially* as white compared to 31% of darker skinned Latinx. So the group of Latinx voters most likely to vote Republican is the group that overwhelmingly self-identities as white. But there’s more...
The study shows lighter-skin Latinx voters are more likely to have antiblack views and the more they see images/news associating Republicans with white people and Dems with black people the *more Republican they get.* So expect them to get *more* Republican under Trump, not less.
