Yup. They won't be voting MAGA because they're "populists". He's delusional if he thinks he can use Hispanics of any kind (particularly immigrants) to flush out the "old guard establishment GOP" and vote MAGA GOP because of culture war issues and foreign policy et al. They have no love for America and American nationalism and while they may be socially conservative to some extent, they are above all else freeloaders and moochers and absolutely will vote for the party that offers them free stuff galore, which is the Democrats.
If Trump mass deports everyone that has come in since Biden took office on 01/20/2021, without due process, that would be based and frankly the only option, and henceforth America and MAGA populism can be saved; otherwise it's just going to be a turd-world salad bowl hole like what Canada has become (go to Toronto for a few days and tell me what % of whites and Muslims you see on a daily basis, for instance), and completely dominated by the globalist liberal party and neocon globalist-marxist puppets like Trudeau.
