This has angered some in the House GOP, and on Tuesday Axios caught House Minority Leader Kevin McCarthy on a hot mic saying “I’ve had it with her.” But Mr. McCarthy knows Ms. Cheney is right. The election wasn't stolen, yet Mr. Trump wants an endorsement of his stolen claim to be a litmus test for every Republican candidate. He’s the one who wants to refight his losing campaign. The better part of political prudence would be for Ms. Cheney to ignore Mr. Trump. But Mr. Trump won’t ignore her. He issued four statements on Monday and three of the four were attacks on fellow Republicans, including one on Ms. Cheney. She may be ousted because she is daring to tell the truth to GOP voters—and at personal political risk. Even as President Biden proposes the largest expansion of government in decades, Mr. Trump is spending his energy settling scores in his own party. He’s thrown his loyal Vice President over the side because Mike Pence refused to pull an unconstitutional stunt to invalidate the pro forma Electoral College count on Jan. 6. As ever with Mr. Trump, everything is always about him.
