This is a sad day for the freedom of speech. Who could have imagined that the same Court which, within the past four years, has sternly disapproved of restrictions upon such inconsequential forms of expression as virtual child pornography, Ashcroft v. Free Speech Coalition, 535 U.S. 234 (2002), tobacco advertising, Lorillard Tobacco Co. v. Reilly, 533 U.S. 525 (2001), dissemination of illegally intercepted communications, Bartnicki v. Vopper, 532 U.S. 514 (2001), and sexually explicit cable programming, United States v. Playboy Entertainment Group, Inc., 529 U.S. 803 (2000), would smile with favor upon a law that cuts to the heart of what the First Amendment is meant to protect: the right to criticize the government. For that is what the most offensive provisions of this legislation are all about. We are governed by Congress, and this legislation prohibits the criticism of Members of Congress by those entities most capable of giving such criticism loud voice: national political parties and corporations, both of the commercial and the not-for-profit sort. It forbids pre-election criticism of incumbents by corporations, even not-for-profit corporations, by use of their general funds; and forbids national-party use of “soft” money to fund “issue ads” that incumbents find so offensive.
