yeah they may frame it as "uncontrolled migration" but given recent events like the Bo French tweet about Indian Americans, "uncontrolled migration" appears to be more of a euphemism for non-white people becoming more present in American society. Hence the desire to roll back a pluralistic democracy and install an ethnonationalist authoritarian that will privilege a certain class of people and punish others. This is at least the animus behind the MAGA core

As for swing voters, they really just wanted inflation to get under control. So they didn't even trade away their rights for DEI or migration control, just inflation. A bit disconcerting to see that people will so easily give away the very rights that people fought decades to have.
