A Welcome, if Partial, Fix

[Commentary] "Hi. I'm the C.E.O. of (Fill in the Blank) Corporation, and I approved this message." If Senator Charles Schumer and Representative Chris Van Hollen have their way, you'll be hearing those sorts of disclosures in political ads for November's Congressional elections.

It is a sensible way for voters to find out which businesses, or unions, are using their treasuries to promote which candidates. And it has become absolutely necessary since the Supreme Court's disastrous ruling last month in the case of Citizens United v. Federal Election Commission. The Schumer-Van Hollen bill is expected to be introduced later this month. Congressional leaders should put it on a fast track so it can be in place in time for this year's midterm elections. It could help keep special interest money in check until the real solution comes: a Supreme Court ruling reversing the deeply antidemocratic Citizens United decision.
