Apparently, this is trending right now.
Obama should resign today. This would make Biden the 45th President of the USA, and thus would invalidate all the millions of dollars in pre-printed merchandise that the Trump camp is readying for #45.
Extend this, and have Biden then resign the presidency within 24 hours, in which case it passes to … the Speaker of the House (right?), and thus it would completely kill Paul Ryan’s hopes of a future Presidency.
Scorched Earth, baby… scorched Earth.
