Former DNR Commissioner Dan Sullivan (R) hints in his resignation letter sent to Alaska Gov. Sean Parnell (R) that he has an eye on public office.


"It has been the honor of a lifetime to serve Alaskans as their Attorney General and Commissioner of theĀ  Department of Natural Resources over the past four years. I want to thank you, as well as former Governor Palin, and the Alaska State Legislature for this opportunity," he writes. "As I explore new opportunities and challenges in the next phase of my life, I intend to seek ways to continue to serve my fellow Alaskans."

Sullivan's likely candidacy will pit him against Alaska Lieutenant Gov. Mead Treadwell (R) and Tea Party candidate and 2010 GOP nominee Joe Miller (R).

A late-July poll showed Treadwell leading the field, but Sullivan and Miller weren't behind by much.

Parnell praised Sullivan in a response letter.

"Dan has been an instrumental part of my administration and his leadership will be missed. I wish him much success in the future," he says.
