We’ve documented what seems like a mountain of Joe Biden “gaffes” at this point.

I continue to wonder why he’s running in his condition.

But it may be getting worse in his desperate effort to stop Sen. Bernie Sanders (I-VT) and knowing that if he doesn’t pull out South Carolina with a big win, he’s pretty much toast.

First, he didn’t appear to know what state he was in. Unfortunately for him, that’s not unusual.

Begs the question: Does Joe Biden know which state he is in? https://t.co/xRyB2qdiMa

Then he told folks at a campaign event that he’d been responsible for the Paris Climate Accord and that he met with Deng Xiaoping on it to pressure China to comply with it.

Joe Biden claimed tonight that he worked with Chinese leader Deng Xiaoping on the Paris Climate Accord.

Except the current Chinese President is Xi Jinping.

From Townhall:

“One of the things I’m proudest of is getting passed, getting moved, getting in control of is the Paris Climate Accord,” Biden told the crowd. “I’m the guy who came back after meeting with Deng Xiaoping and making the case that I believe China will join if we put pressure on them. We got almost 200 nations to join.”

Deng Xiaoping died 23 years ago in 1997 and had nothing to do with the Paris Accord which was signed in 2016.

That was pretty bad.

But he capped it off with a real corker.

He’s running for president, but he told voters in South Carolina that he was running for the Senate.

“You’re the ones who sent Barack Obama the presidency. And I have a simple proposition here: I’m here to ask you for your help,” Biden told voters at the South Carolina Democrat Party’s First in the South Dinner. “Where I come from, you don’t go very far unless you ask. My name’s Joe Biden. I’m a Democratic candidate for the United State’s Senate. Look me over. If you like what you see, help out. If not, vote for the other Biden. Give me a look though, OK?”

The South Carolina debate is Tuesday night, the primary is Saturday. That’s where the rubber hits the road. But it may already be too late for Joe Biden.
