Donald J. Trump stepped into a serious political minefield when he labeled a federal jurist who disagreed with his ban on Muslims entering this country a “so-called judge.”

Mr. President, here’s a flash. More of those “so-called” judges have joined in rejecting your revised travel ban.

The latest rejection comes from the 4th U.S. Circuit Court of Appeals, based in Virginia. The court ruled that the president’s second travel ban is as discriminatory against a certain religion as the first ban. The judges scolded him, too, for seeking to pursue a policy they deem to be unconstitutional.

It doesn’t look good for Trump’s effort to ban entry into this country to those who practice a certain religious faith. The 9th Court of Appeals is set to hear another case that was struck down by a federal judge in Hawaii; the 9th Court had rejected the first ban initially.

The case is likely to end up in the U.S. Supreme Court’s lap. Indeed, the nine men and women on the nation’s highest court well might decide against even hearing the case, which would let the lower-court rulings stand.

We are witnessing from the front row an exercise in the checks-and-balances that the nation’s founders intended in the 18th century when they drafted the U.S. Constitution.

They did well. Don’t you think?
