Yet you seem to forget that considerably fewer younger generation, non-whites vote for the left than their parents do and a lopsided majority of children born to interracial marriages/relationship with one white parent end up voting Republican & breaking the black/Democrat link. You also seem to ignore that majorities of Hispanics in some of the largest, most competitive states (Florida, Texas) voted for conservative, Republican candidates in the last couple of elections. I’m sorry but race, age & even gender demographics are not destiny. People & life are way too complex to be pigeonholed that easily. Reality isn’t that reductive. Has the demographic wave created more of a challenge than might have been the case with our homegrown population & their offspring (which by international standards is regarded as extraordinarily conservative compared to all modern democracies)... to a degree, but no where near enough to favor the left. We still lean well to the right, regardless of demographic nonsense! 😉
Trump received...
Black Vote - 12%
Hispanic Vote - 32%
Asian Vote - 34%
White Vote - 58%
The non-white ethnic percentages who vote Republican have barely changed since the Reagan-Mondale election in 1984, almost 40 years ago.

By the way - the Black Texas Republican who won the seat in a Hispanic Congressional District in 2020 refused to endorse Trump.
