Forget Trump. Congress can make a deal to end the shutdown.

That deal, as many in Washington know and have advocated for months, involves a swap: Shield hundreds of thousands of “dreamers” from the threat of deportation, ensuring them the safe and secure lives they deserve in the country they’ve known since they were brought to this nation as children. On top of that, grant a reprieve to tens of thousands of Hondurans, Haitians and Salvadorans who have lived legally for years in the United States but now face the threat of removal as the administration rescinds their existing protections under the temporary protected status (TPS) program. In return, offer Mr. Trump some money to build his wall.

Everyone gnashes their teeth over that tradeoff, proof that it contains the elements of a plausible compromise. There’s no shortage of House Democrats, reveling in their new majority, who say they will “never” fund Mr. Trump’s wall, nor even a portion of it. Senate Majority Leader Mitch McConnell (R-Ky.), AWOL since the president flipped on a stopgap funding measure to keep the government running last month, remains in his sullen funk, refusing to bring legislation to a vote without Mr. Trump’s say-so. House Speaker Nancy Pelosi (D-Calif.) frames the debate, specifically the wall, in terms of morality — a surefire kiss of death.
