President Joe Biden launched a fresh bid on Friday to bolster support from African American voters, looking to seal up cracks in the Democratic coalition that carried him to victory over Republican Donald Trump in 2020.Biden visited the popular National Museum of African American History and Culture in downtown Washington and greeted his audience by declaring: “Black history is American history.”He and Vice-President Kamala Harris later will meet privately at the White House with the Divine Nine, a group of historically black sororities and fraternities.Harris joined one of those sororities, Alpha Kappa Alpha, when she attended Howard University.On Thursday, Biden met families who had relatives involved in the Supreme Court’s landmark May 17, 1954, Brown v. Board of Education ruling 70 years ago that led to the desegregation of schools.“We learn better when we learn together,” Biden said at the museum.This leads up to Biden’s commencement speech tomorrow at Morehouse College in Atlanta, a historically black school that was the alma mater of slain civil rights icon Martin Luther King Jr.He will attend an event in Georgia today focused on engaging black voters.Democrats are deeply divided over Biden’s handling of the Israel-Hamas war in Gaza, a new Reuters/Ipsos poll found, fraying the coalition that he relied on four years ago to beat Trump.A New York Times/Siena College poll released early this week found Trump winning 20% of the black vote, a sign that he has made inroads into a bloc of voters who have traditionally overwhelmingly voted for Democrats.Biden singled out Trump and other Republicans for attacking programmes aimed at improving diversity, equity and inclusion.He said during the museum visit that the “extreme” Republican and his allies were trying to “erase history”.“My predecessor and his extreme MAGA friends are now going after diversity, equity and inclusion all across America,” he said, referring to Trump’s “Make America Great Again” movement.“They want a country for some, not for all,” he said at the museum, which was opened in 2016 by Barack Obama, America’s first black president, and has since become a Washington landmark.Biden also criticised the “extreme” US Supreme Court which, with three judges appointed by Trump, has issued a string of controversial rulings on abortion, voting rights and diversity.Biden joined Atlanta radio show host Darian “Big Tigger” Morgan on Wednesday and had some sharp criticism for Trump, the former president who is trying to regain the office in the November 5 election.“Look, Trump hurt black people every chance he got,” Biden said. “Black unemployment, uninsurance rates went up under Trump. Trump’s tax plan reinforced discrimination.”“Typical white households got double the cut of the typical black household,” he continued. “They botched the coronavirus (Covid-19) response, leaving black people dead and Black-owned businesses shuttered.”Some Morehouse faculty members and students had wanted the college to withdraw its invitation to Biden over his administration’s staunch support for Israel’s war in Gaza, where the death toll has mounted to more than 35,000.However, the White House said the visit would go ahead as planned.Biden has taken steps that benefit black Americans, such as expanding access to healthcare coverage, and has fostered economic gains that led to record low black unemployment rates and the Child Tax Credit expansion, which helped cut childhood poverty in half in 2021.Opinion polls show the November 5 election shaping up to be a close match between Biden and Trump, making turnout among black Americans – who comprise sizable populations in key battleground states like Georgia, Michigan, Wisconsin and Pennsylvania – a crucial aspect of Biden’s path to victory.Biden’s re-election campaign, in a memo released by senior adviser Trey Baker, said that the president is not taking a single voter for granted.“We are not, and will not, parachute into these communities at the last minute, expecting their vote. Every day, from now until election day, we will continue working diligently to ensure that come November, black voters send Joe Biden and Kamala Harris back to the White House to continue delivering for black America in unprecedented ways,” he said.“We are meeting black voters where they are,” Baker said in an e-mail. “After Donald Trump failed us, no administration has delivered for black America like President Biden and Vice-President Harris.”
