In what may ultimately be one of the hottest primary challenges against a congressional incumbent in the country, a new television ad is on the airwaves, blasting Congresswoman Kay Granger for being out of step with the conservative values of her district.

The 30-second spot, paid for by the Protect Freedom PAC, references Granger’s repeated support for the taxpayer-funding of abortion provider Planned Parenthood and opposition to proposed legislation in Texas to limit abortions.

The real kicker, however, is a line Granger infamously delivered during an interview with liberal network MSNBC, in which she stated, “I am a pro-choice Republican.”

Until just recently, Granger has been unabashed in her pro-choice stance, describing the practice of abortion as “a situation that a woman makes a decision with her own self and her own physician and her own family.”

For the first time in her 23-year congressional stint, however, Granger faces a serious challenge in the Republican primary election by former Colleyville City Councilman Chris Putnam, who has been endorsed by Texas Right to Life—the state’s largest and oldest pro-life organization.

Granger, on the other hand, is touting the support of Texas Alliance for Life, a fake “pro-life” group known best in Austin for killing life-saving legislation behind the scenes while giving political cover to moderate Republicans.

Voters in Congressional District 12, a safe Republican district that stretches from West Tarrant County into Parker and Wise counties, will make their decision in the Republican primary election on March 3.
