U.S. Sen. Lisa Murkowski reports raising more than $307,000 in just more than a month, giving the Republican about $1.8 million heading into the Aug. 24 primary.
The disclosure, filed with the Federal Election Commission, came as GOP challenger Joe Miller touted another high-profile endorsement -- this time from former Arkansas Gov. Mike Huckabee.
Huckabee said in a statement Monday that he believes Miller will "work to help restore constitutional limits on federal power."
Huckabee joins the likes of Sarah Palin and Tea Party Express in endorsing Miller.
Palin's PAC gave Miller $5,000. As of Thursday, Tea Party Express' PAC reported spending more than $123,000 for an ad for Miller, with total spending of around $250,000 expected, spokesman Levi Russell said.
Murkowski's endorsers include the National Rifle Association's PAC and groups around the state.
Miller has said he appreciates the endorsements but the focus of the race should be on bringing limited government.
Huckabee's endorsement calls Miller a former state magistrate and federal judge. Miller's bio shows he served as an acting state court judge and a federal magistrate.
