Since most 'hispanic' voters are against illegal aliens, whom pray on their communities, degrade their job prospects, and crush most schools, that number will be pretty dang small. Even in liberal utopia California, a majority of 'hispanic' voters passed legislation (mostly overturned in courts) to deny benefits to illegals, including schools, bilingual education, immersive education (why include English at all?), and the ever popular illegal aliens with anchor baby road into welfare.
Almost all the activists for illegal aliens are liberals who won't vote for anyone with an (R) after their name to begin with. The others are union activists who see illegals as a gold mine to strip for loads of union dues, and also would never vote for someone with an (R) after their name.
Only a delusional narcissist would imagine that they could basically campaign with a Democrat agenda on the issue and somehow gain 'hispanic' votes. Which is pretty much most of the GOPe field.
I don’t know how many Hispanic voters would like to enforce immigration laws. I do know one Hispanic voter very well who is definitely pissed off at illegal immigrants getting money that eventually comes from our taxes.
I do however think the voting patterns of Hispanics in a general election might be different from the voting patterns in a primary. Specifically I’d be concerned that cross over voters who have no intention of voting for the Republican candidate in November might be motivated to vote in a primary, especially if the primary in their party is not competitive.
I’d also think the new Puerto Rican voters might be a very Democrat and liberal constituency that, as citizens, are all allowed to vote.
