They probably asked him, and he said hell no.
They won't let him run in November. New candidate with a new VP. That's right, Kamala, this is a far as we'll let you go.
I said months ago, I think the Dems are stuck with Joey. They waited too long and “Heels up Harris” is not remotely qualified except for one thing.
What are the Dems options as of May 2024?
Replace Joey, get Harris.
Joey dies in office or has a mental breakdown, get Harris.
Joey breaks down or dies during or just after Dem convention in chi-congo, elections delayed.
Dems use convention to name their candidate, dump Joey and Harris, cheat like hell in Nov, 100 million votes to yet unnamed candidate.
Destroy the economy, start WWII, blame it on Trump after he wins.
My guess, Dems pick option #5.
