Some other ideas:
"Trumps economy got me like…" with a surprised/smiling/impressed black person. Something funny would be good.
"Democrats don't care about black communities" "…as long as we vote" #getwoke picture of a busted shitty black dem community like chiraq or detroit.
"Immigration is a problem" bottom line: "for black communities" maybe a picture of a news article where mexican gang shot up a historically black neighborhood like compton.
"We are more than a voting block" Bottom line: "Democrats don't care as long as we vote" with either a group of blacks, a homeless black person/veteran/or a busted black community.
Any feedback anons?
