Donald Trump is currently in the midst of trying to, as he said last night, “soften” his image on immigration, stating that he will renege on his promises to deport each and every person in the country illegally. To the extent that he is moderating—and it’s unclear how much of a change this really is—it will be because no group of voters outside of his core supporters agreed with him. More importantly, despite over a year of campaigning on the issue, he simply has not convinced anyone—even among Republicans—to flip to his side.
Pew Research Center has polled Republicans and Republican-leaning voters on their position on immigration four times in the last two years—twice before Trump announced his candidacy in June 2015 and twice after. As you can see, Trump’s no legalization view has remained flat, losing considerable ground between March and September before rebounding slightly again this year. But at no point was it the majority view in the party.
