Maybe I'm mistaking your argument, but as I understand what crazed is saying, Trump has leverage because non-sociopaths in Congress might not want to devastate exemplary young people who grew up here and who've put themselves forward to be as American as the law allows them to be. Because any right-thinking person would regard this as heinous injustice, that gives leverage to those who don't care about heinous injustice and just want tax cuts or something. People like crazed and his boy Trump, for example. Hence the leverage that crazed sees.
