One day after Attorney General Adam Laxalt announced he is running for governor, a Super PAC unveiled what it said would be a million-dollar ad campaign to boost the Republican’s candidacy.

Freedom Partners Action Fund, part of the Koch network, asserted it will spend seven figures on cable and broadcast television, amplified by a digital mix of ads, to help define Laxalt. The spot touches on Laxalt’s experience in Iraq and portrays him as a fighter for seniors and kids (Education Savings Accounts?) and against higher taxes.

The buy signals just how important the contest is to national Republicans and how the airwaves and cyberspace will teem with ads for the next year. Freedom Partners Action Fund spent $31.5 million last cycle, including ads trying unsuccessfully to elect then-Rep. Joe Heck to the U.S. Senate.

The Koch network is expected to be active in the contest as is Laxalt’s biggest donor, Sheldon Adelson, who has worked with the organization in past cycles.
