Conservative lawmakers in the U.K. voted on one question, but decided another. Their choice may not make the path for an orderly Brexit any easier, but it may make a disorderly Brexit a little less likely.

The ballot presented to 317 Tory members of Parliament on Wednesday night was straightforward: It asked them whether they had confidence in their party leader, Prime Minister Theresa May. The result — she prevailed by 200 votes to 117 — shows that many clearly don't.

But if the verdict offers May little comfort personally, it shows that MPs understood the real question they were being asked was somewhat different. Were they willing to gamble on Britain exiting the European Union without a deal?
