No. Dems need an issue like racism, so they'll keep it going as long as they can. How do you think white nationalism was brought from its death bed?
It's dem-strategy 101: cause a problem (or make one up) then present dems as the only solution. No fear that never actually fixing the problem will be a problem for them with their voters, because it's always Trump's fault.
And why not? It works with low info dem voters. It works even though dems have been in charge at the white house for 12 of the last 16 years. Still, nothing is ever their fault.
