Joe Biden’s presidential campaign continues to be a circus.

Biden is a gaffe machine who keeps stepping on rakes.

Now Biden got caught in one big lie that has Barack Obama seeing red.

Iranian terror strategist Qasem Soleimani is dead, and Democrats are piping mad.

The left’s reflexive hatred of Donald Trump forces them to take untenable and ridiculous positions.

So because Trump ordered an airstrike that killed a terrorist responsible for the thousands of American deaths, liberals have to find a way to decry the move.

But taking the opposite side of Trump forces people to confront their past record.

That’s the pitfall Joe Biden stepped into yet again.

Joe Biden was quick to criticize Trump, but when he was faced with a question about Barack Obama authorizing the raid on Osama Bin Laden, Biden fumbled.

Biden said he supported that military action, but that’s a lie.

Biden is on record advising Obama not to go through with the attack.

During a presidential debate in 2012 with Mitt Romney, Obama said, “When it comes to going after Osama bin Laden, you said, well, any president would make that call. But when you were a candidate in 2008 … you said we shouldn’t move heaven and earth to get one man, and you said we should ask Pakistan for permission. And even some in my own party, including my current vice president, had the same critique as you did.”

So there’s Barack Obama himself explaining that Biden was against the raid.

Even worse, Biden himself said as much.

In a 2012 video, Biden replied, “He said, ‘Joe, what do you think?’ And I said …’Mr. President, my suggestion is, don’t go.’”

And there it is.

Biden either forgot what he said, or lied.

Either way, it’s a terrible sign for somebody who’s trying to become President of the United States.

Biden’s latest gaffe not only drags Obama’s name back into the political fray, it highlights the fact they’re not thick as thieves the way Biden likes to pretend.

Biden has done everything but beg for an endorsement from Obama, and it doesn’t appear like an endorsement is coming any time soon.

Obama said he wants to stay out of the primary race, so this blunder by Biden doesn’t help.

Biden’s chances of defeating Trump in 2020 appear as slim as ever.

Nobody is enthusiastic about voting for a candidate who can’t remember which state he’s in, can’t distinguish between living and dead female British prime ministers, can’t stop creepily caressing women and little girls, and can’t stop challenging people to push-up contests.

His campaign is off the rails, and it could become disastrous if he’s called before the Senate to testify about his role and his son Hunter’s role regarding the Ukrainian energy company Burisma.

As Biden’s mistakes begin to stack up, his path to victory gets narrower, especially with a far-left media class that doesn’t think he’s “woke” enough.
