Atlas will probably predict that President Biden will fail. Therefore, I would predict Biden to succeed given the community’s track record.
Depends what success means? He'll certainly get some bills passed such as infrastructure and a public option of healthcare, depending on how 2020 congressional elections turn out, appoint liberal or moderate judges and restore our standing in the world. That may fall flat if a recession hits and the public sees his admin as incompetent on the economy.
Biden runs for reelection, faces a rematch with a totally senile Trump.
A 82 year old prez running against a 78 year old former prez? That'll be hard.
