I think the Biden campaign outright said that Hispanics were not part of their path to victory in 2020. The Dems also spinelessly gave in to conservative framing about border crises and jettisoned a policy that was popular–pathway to citizenship, amnesty for Dreamers/those who have been here forever, but more inflow controls. The old ass Dems didn’t trust the American people to grasp nuance and overlook the “open borders” panic even though most people are pretty humane about undocumented immigrants even while nominally against them.
