Former Vice President Joe Biden is still the odds-on favorite to secure the Democratic nomination.

But since his abysmal performances at both Democratic presidential primary debates, Biden has been hit with countless reports that have hurt his campaign significantly.

And now, it appears that even former President Barack Obama has warned Biden about making the biggest mistake of his life.

According to the New York Times, Obama wasn’t sold on the idea of Biden, who served as his vice president for eight years, running for president in 2020.

“You don’t have to do this, Joe, you really don’t,” Obama told Biden before he officially launched his presidential campaign in April.

“Mr. Biden — who thinks he could have defeated Donald Trump four years ago — responded by telling Mr. Obama he could never forgive himself if he turned down a second shot at Mr. Trump,” the Times reports.

Obama huddled with top Biden aides in March to implore they insure that the former vice president does not “damage his legacy” or “embarrass himself.”

Obama and Biden met over lunch last, where the former president urged the White House hopeful to recruit fresher faces to his campaign.

He has communicated his frustration that Mr. Biden’s closest advisers are too old and out of touch with the current political climate — urging him to include more younger aides.

Like Obama, many continue to question whether Biden is mentally fit to hold any public office.

Last week, Biden went full-racist by telling a crowd that “poor kids were just as bright and talented as white kids.”

A few days before that, the former VP mistakenly said the recent mass shootings in El Paso, Texas, and Dayton, Ohio, took place in Houston and Michigan.

Biden was also accused a few days before that of grabbing a young college student after she asked him at a campaign event how many genders there are.

Needless to say, Biden was not happy about the question and grabbed the reporters arm.

When he’s not suggesting a “shooting war” with the GOP or threatening Trump with violence, Biden has been accused by at least four women in recent months of inappropriately touching them without their consent.

Biden’s behavior is so bad that even the mainstream media criticized him after he disgustingly had his hands all over a 10-year-old girl during a campaign stop.

Obama’s No. 2 has also been called out for flip-flopping on several issues, which is a clear attempt to pander to the radical Left now that he’s seeking their vote to become president.

Despite all of this, Biden is still the Democratic front-runner and darling of the Left.

But for how much longer?
