Don is 83 years old. You have to realize that the possibility of his passing while in office are fairly high. That is a simple fact of life.  I fear another Lisa Murkowski type of replacement when he passes. While the governor can no longer make a unilateral decision, the rapid election for a replacement is going to feature the Party favorites.  Getting to vote for a candidate and having a slate of candidates to chose from is not going to be pretty. I'm not enthused who the party favorites might be at this point.
