I remain skeptical. The true test will be what happens when the GOP savages a Democrat nominated Hispanic, whether the loyalty is to the GOP or the ethnic group.
I remember another "natural" GOP constituency, Asians. Then the GOP savaged Clinton nominated Bill Lan Lee (forced busing and affirmative action/quota lover). All of a sudden the GOP became racist and Asians Democrats.
Asians have ALWAYS voted Dem overwhelmingly. It goes back to the late 1800s and perceptions that the GOP was behind the "Chinese Exclusion Acts." (Some of both parties were involved).
But I'll call you on this one. I seem to notice that Hawaii just elected a REPUBLICAN ASIAN WOMAN as its first GOP Gov.!
