Democratic Primaries

If Biden was in government right now that would be different but because he is not he cannot command the attention he should and the power he doesn't have.

Right now Biden needs to be outside but above it all. As the summer comes and the election nears he can take a much more active position. With the two as the face of the Senate Democrats (where the action is) give a unity message and will make them important surrogates later in the campaign season.

As stereotypical as this sounds, people run to Mom when they are sick.
