IOWA CITY, Iowa—A top ally of Hillary Clinton’s campaign says a new ad released by rival Bernie Sanders on Thursday presents a “bizarre” image of America, focused on white voters.
“It’s a significant slight to the Democratic base,” says David Brock, a long-time Clinton supporter who runs several groups aiding her candidacy. “If it weren’t for the picture of Sanders it could be an ad for Donald Trump.”
He adds: “From this ad it seems black lives don’t matter much to Bernie Sanders.”
