Ted Cruz is clearly right over the target.
Despite a pledge to steer clear of endorsing incumbents, Sen. Ted Cruz (R-TX) has financially backed a handful of Senate Republicans through his PAC, including Sen. John Cornyn (R-TX), whose campaign Cruz said that he would not endorse, the Washington Post reports.
Cruz's leadership PAC, Jobs Growth and Freedom Fund, "made only five donations in the first six months of its existence, and all of those dollars went to incumbents."
