I haven't changed much, though I'm not sure whether I've actually moved left on immigration, or it just seems that way since the country as a whole has charged to the right.
Upon further reflection, I've definitely shifted somewhat leftward on economics, maybe very slightly to the right on social issues apart from immigration. I'm also now positive that I haven't shifted on immigration, but my views which probably wouldn't have been controversial at all during the Obama years are probably considered left-wing extremism, since "moderate" on immigration seems to have gone from "we need to reduce illegal immigration but treat those who haven't committed violent crimes like human beings" to "let's restrict legal immigration more but not be
too cruel about it."
