Could spell danger for the DNC if any of it switches to Trump who has already done better than most Republicans with blacks that could make a huge difference. "NEW YORK (Reuters) - Former Vice President Joe Biden, the early front-runner for the 2020 Democratic presidential nomination, has lost support among African-Americans after taking heat on racial issues during the party’s first debate, according to a Reuters/Ipsos poll..... ..... The survey, conducted from Friday to Monday in the days following the debate in Miami, found 22 percent of adults who identify as Democrats or independents said they supported Biden, down 8 percentage points from a similar poll conducted earlier in June. Support for Biden among blacks, a critical Democratic voting bloc, was cut in half, with about two out of 10 saying they backed President Barack Obama’s former vice president, compared with four out of 10 in the June poll." https://www.reuters.com/article/us-...after-debate-reuters-ipsos-poll-idUSKCN1TY1AM
