Biden/Ocasio-Cortez ‘20!
Ain't happening, no matter how much we'd love it. Biden is too old and mentally feeble, and Occasionally Coherent is too young, constitutionally, to be on the ticket.
I'd prefer Warren/O'Rourke (or O'Rourke/Warren) in 2020. A fake Native-American and a fake Mexican. PDJT would have a field day with that!
