A super PAC supporting House Republican candidates announced Monday that it would allocate a total of $10 million to 12 races in its first wave of spending for the general election.

The Congressional Leadership Fund plans to spend nearly $7.4 million in broadcast and cable television ad buys, $1.5 million to build ground-game operations in New York and California, and $1.1 million on digital advertising and other political spending.

“This is the first wave of efficient, strategic ad reservations,” Mike Shields, the fund’s president, said in a statement. “We will continue to add to these buys in the coming weeks, including more television advertising, digital advertising, and further ground troop investments. Our historically strong fundraising has put us in a position to not only protect Republicans in tough races, but also to take the fight to Democrats on their turf.”

Much of the spending announced Monday isn’t scheduled to launch until October, with most ads scheduled to air in the final weeks of the campaign.
