A dozen Republican senators show some spine. It won’t be enough.

REGARDING PRESIDENT TRUMP’S pet project, a wall on the U.S.-Mexico border, the will of Congress is clear. For fiscal 2019, the executive branch may spend $1.375 billion to build a fence-like barrier in one sector of the region. That’s it — and Mr. Trump signed the bill on Feb. 15 to avert yet another government shutdown. What is more, a clear majority of Congress — 245 of 432 sitting representatives and, as we learned Thursday, 59 of 100 senators — has voted to terminate the national emergency Mr. Trump declared so he could devote $3.6 billion of other appropriated funds to a wall.
