He is the face of the party in Theory. But it just doesnt feel like that. He more feels like a place holder to take us away from Trump. But there are Dems who just wont get behind, you have the ones that wont vote to get rid of the Fillbuster, the Infrastructure bill is having problems, there are Dems who have blasted him in public on his handling of Afghanistan and giving the GOP talking points right from their own lips. They are behind him on Covid and his response to that but they have always been strong on covid,
So he seems to be the face of the party but one that his own party does not support fully.
