It is demonstrably true that many Hispanic voters have been in the country long enough not to prioritize the issue so highly. This Politico article summarizes the results of a USA Today/Gallup poll from which these findings come.
As you might surmise, immigrants and first-generation Hispanics care more about immigration than do Hispanics who've been here longer. Ceteris paribus, immigrants and first-generation Hispanics have closer ties to family in other countries.
Gallup concludes that, as both presidential candidates make overtures to Hispanic voters, immigration should not be their main selling point. They note:
Rather, the economy -- specifically, unemployment and economic growth -- is of greatest concern to nearly four in 10 Hispanic voters, while another 21% are most concerned about healthcare.Which statistic suggests many Hispanic voters are concentrated in employment not providing health care.
