I think if he chooses to run he'd be a good chance of being the nominee and could have an advantage especially if Trump wins and is term limited, although I think that Shapiro or Whitmer would be stronger.
The problem for them is the Dem primary is still controlled by black voters. Without doing well with them like Obama, Clinton, and Biden there is very little chance to win. Suburban women still do not comprise enough of the party for Whitmer to win, and enough of the wwc have left which makes it even harder for Shapiro.
