Well....you have to wonder about this element, and if the DNC has a team writing the 'what-if' scenario.
Frankly, I'd have forty different worries, and it'd bother me if we got to the primary season (starting January of 2024), and we had a 'potential-loser' in the seat.
Would they want Harris to move up a 'spot'? NO....I just can't see that scenario being something you'd prefer.
So I'm of the mind....before we get to December....some huge swap-out will occur, and a couple of newspapers will have the whole story laid out.....leading Joe out of the campaign and identifying the replacement 'guy' (Newsom, more than likely).
