And he's not out for the lime light.
Think you have him all wrong.
Someone usually sits in for the VP in the Senate except for a needed vote.
VP has no set bounds.
Chief of Staff is most likely....but VP is fine, too.
You have what I said all wrong. My point was that he would be out of the limelight as Chief of Staff and it is a lot of drudge work not the kind of work that would make good use of his talents.
