Well, the GOP is going to get blitzed on the Latino vote in the General so it really doesn’t matter much.
The likely nominee is Trump and fully 80% of potential Latino voters can’t stand him.

So any talk of any GOP Latino support is just whistling past the graveyard ... an activity that GOP voters engage in WAY too often.
univision poll. ha.
"Competing for Hispanic votes" is a Karl Rove-inspired figleaf for open borders. Rove and others talk disingenuously about trying to capture a share of the Mexican vote, but they'll never get it except among Mexicans from northern Mexico, the prebend of Vicente Fox's business-oriented PAN party. They and Central Americans (who are vote-splitters) are who gave Dubya the 35-40% splits Rove always goes on about, when Dubya was running for governor.
Mexicans from the interior are basically Socialists in the Eastern European sense -- nearly Communists -- and explicitly Communists if they're from the south, where not PRI but the very Red PRD holds sway, where Comandante Cero once led a guerrilla band in recent memory. Worse, Mexicans are "culturally conservative" -- if Grandpa Triunfador voted PRI back in the 1920's, so are his descendants today: they won't switch to the PRD or PAN for any reason. This tenacity goes on for generations, which is how we can tell Rove is lying. He knows better than what he is telling people.
In the States, Mexicans split 70/30 'Rat, that's why LBJ, Slick, and Barky want(ed) open borders.
People from Central and South America, on the other hand, split their ballots about 50/50, interestingly -- which suggests a future immigration policy that tilts away from Mexico and instead takes its intake of Latins from South America through Miami. (Just thinking out loud.)
Oh, and Moslems split 80/20 'Rat. Just in case you were wondering about all that Moslem immigration Barky's been inviting -- and directing disproportionately toward Texas, as part of an attempt to tilt Texas blue.
