Abercrombie, being the Governor, gets to decide who serves in Inouye's former seat until the special election, when the voters will decide. This is the law. No single person decides how long that person serves. But, I maintain that the "reasons" for firing Schatz are very weak, and that the Hanabusa camp has not convinced me why she would do a better job as senator than Schatz is doing right now.
Basically this; I don't have a problem with Hanabusa challenging Schatz, but I don't believe she has a good case for ousting him, and for ideological and seniority reasons, I'd prefer Schatz to stay in the Senate.
I do think that the characterization of Schatz fans by Hanabusa supporters and vice versa is being a bit unfair.
