Except he isn't doing a good job on immigration? Not only is he fucking up so bad with ICE that abolishing ICE is now somewhat mainstream opinion (whilst deporting less illegal immigrants than Obama), he fully supported expanding H1B visas and said that there is no talent in America so they have to import it. If a Democrat said this miggers would cry nonstop about how the left is bragging about committing White Genocide. Conveniently miggers have memoryholed this because they are such pathetic cucks to Trump. As long as they get to see stories and videos of ICE brutalizing brown people online they clap like seals, even if Trump is importing infinitely more of them because his oligarch buddies need that cheap labor
Immigration itself isn't even inherently a right or left issue. Most Republicans, Trump included, are totally fine with mass immigration as long as it's legal because it strongly benefits their corporate overlords. Some of the more anti neoliberal Dems like Bernie Sanders and Ro Khanna are critical of Trump's h1b visa policy because corporations are using it to basically import a slave caste.
