Republicans in the U.S. Senate voted unanimously Monday and again on Tuesday to block adoption of the Disclose Act, Democratic Senator Sheldon Whitehouse’s legislation to require disclosure of political donations of more than $10,000 within 24 hours of the money being spent. The votes were no less remarkable for having been predictable. For years, congressional Republicans had vowed that disclosure of donations and spending was the one sure route to an honest campaign-finance system. Senate Republican leader Mitch McConnell, the field general who for two decades has organized the party’s attacks on campaign-finance regulation, including the McCain-Feingold reforms, once spoke eloquently of the sanctity of the First Amendment and of the merits of disclosure. What’s more, because McConnell in the 1990s had also come around to opposing constitutional amendments against flag burning, he had credibility as a First Amendment champion.
