The Associated Press reported that Biden said in October that he wouldn’t promise to serve just one term but that he wasn’t necessarily committed to running for another four years.

“I feel good and all I can say is, watch me, you’ll see,” he told the AP at the time. “It doesn’t mean I would run a second term. I’m not going to make that judgment at this moment.”

You should really read your sources.

Holy shit you should be fucking so embarrassed. That link literally says, right in the first line, that it is just "reportedly" it's not him being quoted. It literally confirms what the other poster said and absolutely contradicts what you said.

It's okay to be wrong, but fuck man, you shouldn't of read at least the first line of your sources to make sure they support your claims when you submit them. That's just mind numbingly dumb.

Nowhere in this article Biden says he will Serve only one term. He basically said that it's an option - nothing more.
