Obama was also “losing” at this point before his re-election
Obama was about 46% and trending upwards at this point, Biden is 37% and trending downward. This is a pretty nice visualization of historical presidential approval ratings plotted with Biden’s. Takeway is while other presidents have tanked way harder (Nixon, Dubya, HW), Trump and Biden are basically tied for historical unpopularity on a consistent basis. Biden did hit mid 50s as he came in to office where most presidents get a bump, Trump didn’t even reach 50.
