The Senate has just sworn-in Sen. Daniel Inouye (D., Hawaii) to be President Pro Tempore of the United States Senate. That puts him third in the line of succession to the presidency.

Should we rethink this? The President Pro Tempore is by its nature as much a ceremonial role as a substantive one, and its occupant is almost certain to be of advancing years.

Should we put put the Senate majority leader in that slot instead? I know, I know: President Harry Reid. The mind boggles.
