The National Republican Congressional Committee has helped fund some of Flores’ TV ads, which began about a month out from the special election. The Congressional Leadership Fund, the top super PAC aligned with House GOP leadership, recently launched $200,000 worth of TV and digital ads supporting Flores. The national conservative group FreedomWorks has a $150,000 investment on behalf of Flores. The Republican National Committee has taken the lead on the ground, boasting over 16,000 doors knocked and nearly 50,000 phone calls made since May 1. And the Texas Republican Party, whose chair and vice chair endorsed Flores early on, has sent out at least four mailers in the district.
