Former Alaska Governor Sarah Palin said it was not surprising that the “cannibalistic” members Washington’s Republican establishment would turn on Sen. Ted Cruz (R-TX) for living up to his campaign promises of defunding and repealing Obamacare.

Palin noted that many Republicans made such promises to get elected, and that it was “extremely disappointing,” but “not surprising” that the “GOP elephants” “would turn on a senator who is fulfilling his campaign promises.” Palin said senators like Cruz and Sen. Mike Lee (R-UT) were fighting for the “will of the people,” “liberty,” and “economic justice” by opposing an Obamacare bill that will hurt working class Americans.

Palin said her father is a science and natural history teacher, but he never taught her that elephants could eat their own.

“You are a teacher, and you never told me that elephants were cannibalistic,” Palin said to her dad. “I wish I would’ve known. Then we would have had a different tactic in the way that we do campaigning.”

Palin said “enough is enough” with Obamacare and that it was time to “undo” the law and implement a patient-centered and market-based healthcare plan.

In her exclusive op-ed for Breitbart News on Saturday, Palin blistered Washington’s permanent political class, especially its Republicans:

Those of us who hang in there supporting a major political party with our energy, time, and contributions would like to believe that that party would praise principled conservatives like Ted Cruz and Mike Lee for following through on campaign promises. We’d like to believe that the GOP establishment would applaud the way these bold leaders have rallied the grassroots to their cause. But, no, such praise would require a commensurate level of guts and leadership, and the permanent political class in D.C. is nothing if not gutless and rudderless.

Fox News Sunday host Chris Wallace said he received unsolicited opposition research from Republicans attacking Cruz before his weekend broadcast. Palin, whom the Republican establishment has repeatedly attacked more than any other conservative, demanded that Wallace reveal the names of the “anonymous” sources.
