On a related note:  Walker is clearly a one-term governor.  There is no way he will be able to re-create the coalition of voters that elected him the last time.  He could try to run as a Democrat, but he will lose even more independent voters, and he will have to get past Mark Begich for that nomination.  You think the Democrats will be happy with NOT fielding a candidate again?  No way.  And of course he has no shot at a Republican nomination (and never has).  So he enters a three-way race against Begich, and who...(Mayor) Dan Sullivan?  Mead Treadwell?  I don't know.  In any case, the oil and gas industry will be throwing a huge amount of money against him.  I'm sure Begich will be chomping at the bit to get in there and take advantage of the situation...
