Having a democracy is a long term benefit - addressing more pressing issues like police brutality and superfund sites (that are almost exclusively in predominantly black neighborhoods and cause elevated health issues) are probably going to be more compelling on a statistical level.
Also, I don’t know how many times this needs to be said but shaming black voters for demanding policy changes and daring not to vote D is fucking stupid and infantilizing… some politicians are guilty of this but it’s mostly pundits and those pundits are fucking dumb.
As always, Biden is clearly better than Trump, but give voters a reason to be excited for Biden rather than just fearful of Trump. Excitement drives voter turnout.
