BUCKLEY v. VALEO Opinion of BURGER, C. J. mate and substantial, that purpose cannot be pursued by means that broadly stifle fundamental personal liberties when the end can be more narrowly achieved. The breadth of legislative abridgment must be viewed in the light of less drastic means for achieving the same basic purpose." Shelton v. Tucker, supra, at 488. In light of these views,1 it seems to me that the threshold limits fixed at $10 and $100 for anonymous contributions are constitutionally impermissible on their face. As the Court's opinion notes, ante, at 83, Congress gave little or no thought, one way or the other, to these limits, but rather lifted figures out of a 65-year-old statute.' As we are all painfully aware, the 1976 dollar is not what it used to be and is surely not the dollar of 1910. Ten dollars in 1976 will, for example, purchase only what $1.68 would buy in 1910. United States Dept. of Labor, Handbook of Labor Statistics 1975, p. 313 (Dec. 1975). To argue that a 1976 contribution of $10 or $100 entails a risk of corruption or its appearance is simply too extravagant to be maintained. No public right to know justifies the compelled disclosure of such contributions, at the risk of discouraging them. There is, in short, no relation whatever between the means used and the legitimate goal of ventilating possible undue influence. Congress has used a shotgun to kill wrens as well as hawks. I The particular verbalization has varied from case to case. First Amendment analysis defies capture in a single, easy phrase. The basic point of our inquiry, however expressed, is to determine whether the Government has sought to achieve admittedly important goals by means which demonstrably curtail our liberties to an unnecessary extent. 2 The 1910 legislation required disclosure of the names of recipients of expenditures in excess of $10.
