I assume by "military US Senator" who refer to Senator Sullivan.  I can firmly attest to getting answers from his staff anytime I call, be it DC, Anchorage or Fairbanks.  I can also attest to the effectiveness of his Fairbanks staff. 

I voted for Senator Begich in 2012 because I found him to be highly dedicated and effective and thought he deserved to remain in office.  Having said that, I honor the choice of Alaskans and work with whoever is in office.  I may not agree with everything a Senator or Congressman supports (and that included Senator Begich), but that's politics.  

Senator Sullivan is doing a pretty good job and IS response to constituents. On the other hand, I find Senator Murkowski to be secretive and difficult to obtain answers from, not just on occasion but virtually anytime I call.  The standard line in her office is, "I'm sorry but the senator hasn't stopped by to discuss that issue with me yet".  I can assure you that Senator Murkowski NEVER does that.
