Without the support of Blacks in the recent Democratic Party primaries, Joe Biden would still be the political failure in U.S. Presidential campaigning that he had always been. As the Republican political pro, Pat Buchanan, wrote of Biden on March 5th,
"Before last Saturday, he had not won a single primary in three presidential campaigns." That "last Saturday" referred to the South Carolina primary. Biden's first-ever win of a Presidential primary turned Biden's dead-in-the-water 2020 Presidential campaign into an almost-certain win of the Democratic Party's Presidential nomination.
The vast majority of the votes for Biden in the South Carolina primary came from that state's black Democrats, who are the majority of that state's registered Democrats. (Sanders's win of that state's white Democrats was by a smaller margin.) The Democratic National Committee and its 700+ superdelegates and its members of Congress (representing the Party's billionaires, who finance their careers) had been waiting for this moment before they would become more public about their backing of Biden to be their nominee; and so the official endorsements started suddenly then to pour forth, as if Biden already
were the Party's nominee. Consequently, going into the March 3rd Super Tuesday primaries in 14 states, the opinion polls, which had, until then, shown Sanders as being likely to win almost all of the states, turned suddenly to show Biden as being likely to win almost all of them — which then did happen.
By as late as February 9th, which was the time by which it became clear that Bernie Sanders had won the most votes in the February 3rd Iowa caucuses,
the national polls of Democratic Party voters had shown Joe Biden strongly as #1, with Bernie Sanders a distant #2 nationwide; but, then, promptly after February 9th, the polls showed a huge lead for Sanders as the new #1, and Biden as being around 8% below him and the new #2; but, then, Biden won the South Carolina primary on February 29th, in a landslide and now he is
projected by fivethirtyeight dot com as being 88% likely to win the nomination on the first ballot at the Convention, and as being around 10% likely to get the win of the nomination on a second ballot, and Sanders as having the remaining 2% as being his likelihood to become the Democratic Party's nominee.
