Soooo if millions of illegals enter the voting rolls....then you have, with those numbers a 56% Dhimmicrat majority.
but you miss a couple of things: you are assuming “millions” more into Texas, and that’s not reasonable. You are also assuming this invasion wouldn’t drive more whites, more blacks (post Obama) and more existing Hispanics away from the Dem Party - and it certainly would.
The real demographic problem in this country is not Republicans with Hispanics and women, it’s the Democrats with whites in general, and certainly married whites.
That assumes Latinos are racist voters like blacks.
There’s no evidence of it.
