ANCHORAGE -

A retired U.S Air Force sergeant has made his official bid for Alaska’s 2014 U.S. Senate seat, running against Democratic incumbent Mark Begich.

John Jaramillo has filed his intent to run for the Senate seat as a Republican candidate in the August 19 election. His filing makes him the fourth republican to run against the Democratic incumbent in a race that could determine the Democrats’ ability to keep control of the Senate, whereas a Republican win could switch the chamber’s control to the GOP.

According to a letter of intent to run, Jaramillo writes he “has an uphill battle,” as a disabled veteran, using all his own money to finance his campaign.

According to Jaramillo’s LinkedIn profile the candidate summarizes, “If you want someone in office who values freedoms (like owning and carrying any gun you want) or does not lie about trying to create a carbon tax, I am the person to vote for,” Jaramillo wrote. “I do what I say.”

Jaramillo joins three other Republican candidates, including Joe Miller, former Commissioner of the Alaska Department of Natural Resources Dan Sullivan and current Lt. Governor Mead Treadwell.
