The formula is an old one, to get power, the fascist far right needs an "other" to hate on, for the Nazis it was the Jews, for the UK when it got out of the Eu is was non white immigrants...and of course here in the US it is those crossing the border illegally. America deliberately had porous borders after the Bracero Program was abolished...and those folks who lived and worked in the US for decades need a path to citizenship, and of course, the American people expect and deserve strong borders.
