“young ...single women by almost 40 points, Hispanics by almost 40 points, blacks by more than 80 points.”
All the usual suspects, IOW.
Big deal.
All those who want more for nothing.
Single women - substituting govt for a husband - stability. Single women look to govt as to what to do, and women generally are more submissive to authority figures.
Latinos - amnesty / easy citizenship for their vote. Reclaiming the southwest.
Blacks - never ending welfare and favoritism. Reparations not called reparations, and they don’t want that gravy train to ever end.
