Democrats have often supported Rube-Goldberg-inspired campaign-finance regulations, some based on a conviction that all political money is bad, others based on the belief that only the way their opponents raise money is bad.

It’s what Republicans for years had said they wanted. Hypocrisy is a bipartisan affliction. But congressional Republicans have escaped the outer orbit of expediency with this week’s votes.
