I could see them getting close to or possibly hitting 40% if Democrats really tank in 2024. By a majority? That would either require an enormous realignment or the Democrats actually going the way of the whigs. Too many on this forum act as though Latinos are a monolith of “ackshully really conservative” voters who just haven’t “figured out” that they’re Republicans, which is about as silly as the narrative that rural white voters in Kentucky and West Virginia are actually left-wing and just haven’t figured it out yet or been convinced properly.
Never is a long time, so I’d say “later than 2036” should be an option.
Edited the poll, I don't think Democrats would necessarily have to tank for that to be the case. 2004 was a pretty close election and W got north of 40% and the Latino vote is only more Republican in some places like South Texas then it was back then. Given current trends I don't think it's necessarily outside the realm of possibility, I've even seen some polling that shows Republicans with an outright lead with Latino voters going into the midterms.
