Sullivan is a reflection of his "resume" which in turn reflects no expertise, commitment or passion in or to anything.  He even managed to discount the single, possible item on his resume, being a Marine.  He negated that part by sending an open letter to the Iranian leadership with 47 of his fellow GOP senators.  A core, repeat, core tenet of military membership in ANY service is you do not bypass the chain of command.  In this case he violated that as completely as one possibly can.  So it is no real surprise that his loyalties reside anywhere but with the citizens of Alaska.  He's never really had any to much of anything in the first place.
