The Dems goal was to add to the 90% Dem / 10% R voting breakdown that the black American community has had. The problem with that calculus is that the black American population has stagnated at 13% for decades, so that well will dry up as long as the population stays at 13%.
However, you have the Hispanic population growing that will drown out that 13% black population, and in no way they will vote 90%/10% as the black population has. More like (as a worst case scenario) 65% D / 35% R as a starter, and with the R% increasing and D% decreasing over time.
Hispanics aren't going to go along with drag queens teaching their kids or men who chop off their genitals and claiming to be women having high positions of power.
The black population -- they will never get it. The Hispanic population, I have more hope.
While Blacks comprise 12% of the total population of the US, African-American women comprise 14% of the child bearing population. And African-American women account for 36% of all abortions preformed in America.
