from the hill article:

So Biden never explicitly made a one-term promise during the campaign

ok. Look I’m not trying to pick a fight, I just never heard biden say that and wondered what I’d missed. The Hill article goes on to state:

but he certainly implied it with the language of “transition.”

yeeaah, uh, I’m going to vote for him because < HAHA FUCKING HELLSCAPE PROJECT 2025 > either way

“It’s been memory holed”

No, your own source states that that was never announced. It was talked about within the party. There was never a public announcement to the American people stating that he would not run as an incumbent. Every source reporting on that was and is reporting on unsubstantiated hearsay never set into stone.

If you’d like to compare, Trump is tagged at 30,573 verified lies only during his time in office, not even counting statements made on either campaign trail.
