That spending is being supplemented by Heritage Action itself, which exclusively told Fox News Digital that it has spent $1.8 million on voter engagement in Nevada and New Hampshire. Both of states have high-profile Senate and House races this year that could determine which party holds power in Congress.
"There are conservative candidates and conservative polices on the line," said Jessica Anderson, Heritage Action's executive director. "Let's go and get this done and win back a [congressional] majority for the right reasons and frankly with the right people."
In contrast, the Senate Leadership Fund, a super PAC closely aligned with Sen. Majority Leader Mitch McConnell, R-Ky., announced last month it was cutting nearly $8 million in ads that it had reserved in Arizona throughout Election Day.
"We think he's got a real shot. We think that this race is winnable," Anderson said of Masters. "We think that other conservative and Republican establishment groups should come back to Arizona, they should take a second look at the state and realize everything that's at stake."
Outside of Arizona, Sentinel is spending $1 million to boost GOP Senate nominee Herschel Walker in Georgia. The super PAC is also running nearly $1 million worth of negative ads against Democratic Sens. Mark Kelly of Arizona and Maggie Hassan of New Hampshire over high gasoline prices.
