THE SEPTEMBER SURPRISE:

The switch could be done at the convention – but that requires 300 delegate signatures, and would open the door to a lot of politicking over several weeks by other potential candidates. It would make ’68 look like a picnic, and potentially put Michelle in the grubby position of seeking support just like everyone else.

But should Biden be incentivized to suddenly declare a new health issue that leads him to announce a week or two after the convention that he will continue his term but will not be running, suddenly we have one of those crises that should not be wasted. Rising above it all and quelling the haggling, Michelle – with her 91% popularity among Democrats and 68% nationally when she left the White House, and with the Obama fundraising and political network and job experience – can accede when pressed, for the good of the country, to graciously accept her grateful party’s nomination.

The challenge will be to navigate the various obscure state laws setting hard to determine deadlines for ballots in time to be printed and mailed to voters overseas. In sum, as Washington, D.C.-based election lawyer Ronald Jacobs helped to unpack, while party rules dictate how the nominee is selected, state law dictates when the party can make that change. For many states, those laws are woefully unclear. And even where the law is clear, a court could step in (and has) to force the state to change as they did in New Jersey.

Past legal rulings seem to indicate that August 27 isn’t a problem, but Oct. 1 may be too late (though the likelihood of any court having the fortitude to tell half the country their nominee can’t be on the ballot seems unlikely). Figure two-plus weeks after the convention to be the last safe opportunity to switch.

Exit quote: “In London, where betting on American politics is legal, more bets recently were placed on Michelle Obama becoming president than on Biden, and she remains in second place in the RealClearPolitics Betting Odds Average for the Democratic nomination. What do those bettors know that American pundits don’t?”
