They know, in their timid breasts, that they would have howled with indignation if Barack Obama had declared a national emergency in such a circumstance. As they stare at their coffee cup at breakfast, the thought occurs to them that a future left-wing president could make dangerous use of these same powers—because Speaker Nancy Pelosi rubbed that fact in their face. Some of the brighter ones might even realize that emergency powers are a favored tool of authoritarians everywhere.

But they are afraid. They are afraid of being primaried. They are afraid of being called out by the bully whom they secretly despise but to whom they pledge public fealty. They are afraid of having to find another occupation than serving in elective office. And the most conceited of the lot—and there are quite a few of those, perhaps more in the Senate than in the House—think that it would be a tragedy if the country no longer had their service at its disposal.
