I would venture that Tammie Wilson is sympathetic to constituents' concerns because she's in a safe, right-leaning district.  Not mentioned is the fact that OCS is a political breeding ground for the left  (e.g. Tom Begich, Bettye Davis, Karen Perdue, just to name a few).  I figure that in some districts, taking on OCS as a legislator who has to stand for re-election every two or four years is tantamount to painting a bullseye on your back.
