I get the impulse and it would be amusing, but I have a feeling people are sick of "dynasty" Dem candidates for president (Hillary after her husband, Biden/Harris after each being VPs.) Feels like his legacy and appeal has kind of faded too. He was an exciting first-time candidate and good-enough incumbent, but third term?
Handing your own power down to yourself — as is the case when a VP wins the primary and presidency, or Obama running for a third term — is not a “dynasty”.
