Politically, Biden's dropping out creates all sorts of uncertainty.

Procedurally, however, what happens how is extremely clear: The DNC will use its convention to officially designate its nominees for president and vice president, and those people will appear on the ballot in all 50 states, DC, etc.

A summary of state ballot access laws, from the officials who run the elections, is at https://www.nass.org/sites/default/files/reports/summary-ballot-access-laws-president-june-2024.pdf

It would have been much more complicated if this had occurred after the convention.

I’m not an American, but my advice to American progressives is simply this:

Now’s your chance. If you don’t help elect the first African American woman to the Presidency, you’re full of shit.

That woman is your only chance to save American democracy, so you better get behind her.

Trump is now the oldest POTUS candidate ever nominated by a major party.

He has repeatedly confused Biden with Obama and Nikki Haley with Nancy Pelosi. He fell asleep at his criminal trial.

Will the media scrutinize his age & mental decline with the fervor it focused on Biden?

"You shouldn't depend on drugs to function!"

Yeah, well, congrats on being that one healthy white guy that all of our medicine is apparently based on.
