BUCKLEY v. VALEO Per Curiam We are not unmindful that the damage done by disclosure to the associational interests of the minor parties and their members and to supporters of independents could be significant. These movements are less likely to have a sound financial base and thus are more vulnerable to falloffs in contributions. In some instances fears of reprisal may deter contributions to the point where the movement cannot survive. The public interest also suffers if that result comes to pass, for there is a consequent reduction in the free circulation of ideas both within " and without 86 the political arena. There could well be a case, similar to those before the Court in NAACP v. Alabama and Bates, where the threat to the exercise of First Amendment rights is so serious and the state interest furthered by disclosure so insubstantial that the Act's requirements cannot be constitutionally applied.s" But no appellant in this case has tendered record evidence of the sort proffered in NAACP v. Alabama. Instead, appellants primarily rely on "the clearly articulated fears of individuals, well experienced in the political process." Brief for Appellants 173. At See Williams v. Rhodes, 393 U. S. 23, 32 (1968) ("There is, of course, no reason why two parties should retain a permanent monopoly on the right to have people vote for or against them. Competition in ideas and governmental policies is at the core of our electoral process and of the First Amendment freedoms"); Sweezy v. New Hampshire, 354 U. S. 234, 250-251 (1957) (plurality opinion). s6 Cf. Talley v. California, 362 U. S. 60, 64-65 (1960). 87 Allegations made by a branch of the Socialist Workers Party in a civil action seeking to declare the District of Columbia disclosure and filing requirements unconstitutional as applied to its records were held to be sufficient to withstand a motion to dismiss in Doe v. Martin, 404 F. Supp. 753 (1975) (three-judge court). The District of Columbia provisions require every political committee to keep records of contributions of $10 or more and to report contributors of $50 or more. 85
