From an Institute for Free Speech symposium on the 50th anniversary of Buckley, which I'll be cross-posting over the next couple of weeks; this is by the leading media lawyer Floyd Abrams (Cahill Gordon & Reindel LLP), who has argued over a dozen First Amendment cases before the Supreme Court:
As we approach the fiftieth anniversary of Buckley v. Valeo, I'm reminded of a comment made by Joel Gora, who argued the case for Senator Buckley and Senator McCarthy. He correctly observed that many academics have treated Buckley as a "stain."
This characterization is as unfortunate as it is wrong. For those of us who believe that political speech deserves the highest level of First Amendment protection, Buckley remains not a stain but a shield—one that has protected the fundamental right of Americans to influence their government through both speech and spending.
The decision has wobbled, certainly. It has been criticized from both the left and the right, with some believing it went too far in protecting speech and others convinced it didn't go far enough. But through five decades of assault, Buckley endures, and with good reason: at its heart lies a principle so fundamental to our democracy that even its critics struggle to refute it entirely.
