Joe Biden, former U.S. vice president and now a Democratic presidential candidate, has made several controversial comments that alienate young African American voters—he does not inspire their confidence, according to a report in USA Today on July 8.

“[Young black voters] are going to have some reservations about Joe Biden,” said Chryl N. Laird, assistant professor of government at Bowdoin College, who also alluded to the “moments of problematic comments or statements” issued by Biden.

For example, in May, Biden told African American radio host Larry McElvey, “If you have a problem figuring out whether you’re for me or Trump, then you ain’t black.” Many found his comment outrageous, forcing his campaign adviser to suspend the interview. Biden later apologized for the bitter episode.

This comment came after several weeks of interviews with Biden that were plagued by confusion, long pauses, losing track of conversations, and uttering meaningless phrases. His campaign team preferred that he not continue to appear on air.

Biden’s many shortcomings at age 77, lead to doubts about his cognitive ability. He has already been tested for it, but his campaign refuses to release the results, according to The Federalist, casting a shadow that suggests possible dementia.

Biden is also being held to account for the various legislations he promoted by tightening up laws during his political tenure against African Americans. In making a historical recount, it is necessary to remember that the Ku Klux Klan and the Jim Crow slave laws were a Democratic invention, a party that Biden will represent at the polls next Nov. 3.

Although African Americans in the past have tended to vote for Democratic candidates, the trend has changed substantially. U.S. President Donald Trump won the 2016 election receiving 12 percent of the African American community’s votes, 8 points more than previous Republican candidates. This year it is estimated that the votes for his re-election will rise to 20 percent.

A Pew Research Center study this year showed that the majority (68 percent) of black Democrats described themselves as moderate or conservative, which would imply that their vote would be for the re-election of President Donald Trump.

Famous African American rapper Kanye West expressed his strong support for President Trump’s re-election. He rejects the decision to vote based on race, claiming that it would be “mental slavery.” “I’ve never made a decision based on my color alone,” West said. “That’s a form of slavery, mental slavery,” he said, according to Deseret News.
