Presumptive Democrat nominee Joe Biden’s presidential campaign is in serious peril after the geriatric human gaffe machine stepped in it big time.

The former vice president who has been carefully managed by his handlers since he vanquished Bernie Sanders is at the center of a growing firestorm over racist comments that he made during an appearance on a radio show with a national black audience.

At the end of his chat with rapper/host Charlamagne tha God on “The Breakfast Club” the 77-year-old Beltway insider who has presented himself as the champion of black people made what could be a fatal gaffe.

According to Biden:

“If you have a problem figuring out whether you’re for me or Trump, then you ain’t Black.”

And in an instant, all of the meticulously constructed credibility with black voters that was constructed by influential African-Americans like Democrat Rep. Jim Clyburn was cast to the wind after Biden imploded with one of his trademark gaffes.

With all of the hype of being the heir to Barack Obama’s legacy possibly squandered in mere seconds, lunchbucket Joe’s inflammatory comments set social media ablaze and have possibly run his White House bid into the rocks.

How serious was Biden’s monumental blunder?

The candidate was forced to immediately grovel to the same black leaders who only yesterday were firmly behind him in his bid to prevent President Trump’s reelection.

In a story that was transparently timed to hit the evening news cycle, Biden apologized.

Via Fox News, “Joe Biden expresses regret over ‘you ain’t black’ comments: ‘I shouldn’t have been so cavalier’”:

Joe Biden expressed regret Friday during a call with black business leaders for suggesting in an earlier interview that African-Americans unsure about whether to support him or President Trump “ain’t black.”

“I shouldn’t have been so cavalier,” Biden said in an afternoon phone call with the U.S. Black Chambers, addressing the controversy within seconds of the session starting.

The public attempt to walk back the remarks underscored how explosive the issue became for the presumptive Democratic presidential nominee’s campaign in a matter of hours, at a time when he’s working to unite the party and avoid the kind of internal divisions that helped Trump win in 2016.

Biden said he understands the comments sounded like he was taking the black vote “for granted” but insisted that wasn’t the case.

“I shouldn’t have been such a wise guy,” Biden said. “… No one should have to vote for any party, based on their race or religion or background.”

Team Biden’s swift damage control is likely to please Rep. Clyburn’s influential collection of black leaders but his comments may not be so easily forgiven by voters in the crucial demographic that Democrats have long taken for granted.

The controversy comes at a terrible time for Biden who despite his senility and history of corruption, has had the wind in his sails after the DNC-engineered destruction of Bernie and his movement and Barack Obama’s vow to substitute for the housebound candidate on the campaign trail.

Now all bets are off and an unpleasant surprise at the party’s virtual convention is an increasingly likely possibility.
