Actually when it comes to hispanic voters while Trump did better than Romney,he was still about typical for a republican candidate.Obama got over 2/3 of the hispanic vote but then again dems do well with minorities overall.Problem is hispanics tend to be oversimplified.There are differences between mexicans for example and cubans.The way Trump might be viewed among hispanics of California who largely tend to come from Mexico and or Central America might be different than hispanics of Florida who largely come from Cuba.In fact the main reason why Trump did somewhat better is probably because of the decline in the number of minority voters in 2016.Why that was the case is hard to say most likely a combination of voter apathy and the fact that if you're a democrat in California you might as well not vote.The odds of a republican winning California are close to nonexistent today Arnie only won because he ran as himself.He could have ran as an independent and they still would have elected him.
