GOP builds massive shadow army in fight for the House

TUSTIN, Calif. — Republicans have amassed a sprawling shadow field organization to defend the House this fall, spending tens of millions of dollars in an unprecedented effort to protect dozens of battleground districts that will determine control of the chamber.

The initiative by the Congressional Leadership Fund, a super PAC aligned with Speaker Paul Ryan (R-Wis.), now includes 34 offices running mini-campaigns for vulnerable Republicans throughout the country. It has built its own in-house research and data teams and recruited 4,000 student volunteers, who have knocked on more than 10 million doors since February 2017.
