content-neutral, eliciting only “intermediate” scrutiny. Turner Broadcasting Sys., Inc. v. FCC, — U.S. —, —-—, 114 S.Ct. 2445, 2458-59, 129 L.Ed.2d 497 (1994). The proper categorization of Rule G-37 is not clear-cut. As petitioner points out, under the everyday meaning of the word “content”, the rule appears to be content-based, as it restricts only messages that concern one “topic”, specifically, financial contributions to political campaigns. Cf., e.g., McIntyre v. Ohio Elections Comm’n, — U.S. —, —, 115 S.Ct. 1511, 1529-30, 131 L.Ed.2d 426 (1995); Consolidated Edison Co. v. Public Serv. Comm’n of New York, 447 U.S. 530, 537, 100 S.Ct. 2326, 2332-33, 65 L.Ed.2d 319 (1980). But the Supreme Court does not regard a rule’s use of subject-based categories as automatically establishing it as content-based. The critical issue is whether the state’s justification for the distinction is the “content” of the speech itself or some other concern:
The principal inquiry in determining content neutrality ... is whether the government has adopted a regulation of speech because of disagreement with the message it conveys.... Government regulation of expressive activity is content neutral so long as it is “justified without reference to the content of the regulated speech.”
Ward v. Rock Against Racism, 491 U.S. 781, 791, 109 S.Ct. 2746, 2754, 105 L.Ed.2d 661 (1989) (quoting Clark v. Community for Creative Non-Violence, 468 U.S. 288, 294, 104 S.Ct. 3065, 3069, 82 L.Ed.2d 221 (1984)) (emphasis added). Compare, e.g., Turner Broadcasting, — U.S. at —, 114 S.Ct. at 2467 (content-neutral regulation), and Renton v. Playtime Theatres, Inc., 475 U.S. 41, 106 S.Ct. 925, 89 L.Ed.2d 29 (1986) (same), with City of Cincinnati v. Discovery Network, Inc., — U.S. —, —, 113 S.Ct. 1505, 1517, 123 L.Ed.2d 99 (1993) (content-based regulation), and Boos v. Barry, 485 U.S. 312, 108 S.Ct. 1157, 99 L.Ed.2d 333 (1988) (same).2
This regulation’s goals could well be described as content-neutral. Contributions and solicitation of contributions have two aspects. They may communicate support for a candidate and his ideas, but they may also be used as the cover for what is much like a bribe: a payment that accrues to the private advantage of the official and is intended to induce him to exercise his discretion in the donor’s favor, potentially at the expense of the polity he serves. The SEC clearly rested its approval of Rule G-37 on a wish to curtail this latter function. In language tracking that of § 15B of the Exchange Act, 15 U.S.C. § 78o-4, it explained how the limits would, in its judgment, “prevent[ ] fraudulent and manipulative acts and practices, as well as the appearance of fraud and manipulation”, SEC Approval Order at 26, perfect the mechanism of a free and open market for municipal securities, id. at 29, and “promote just and equitable principles of trade”, id. at 30. Petitioner himself describes these goals as “non-speech-related.” Petitioner’s Br. at 27 n. 14.
These purposes are quite different from some of the ones that have triggered strict scrutiny in other cases involving political contributions. In Buckley v. Valeo, the interests “served by the Act include[d] restricting the voices of people and interest groups who have money to spend and reducing the overall scope of federal election campaigns”, as well as “equalizing the relative ability of all voters to affect electoral outcomes”. 424 U.S. at 17, 96 S.Ct. at 634. See also id. at 25-26, 96 S.Ct. at 637-38 (referring to “ancillary” interest in “serv[ing] to mute the voices of affluent persons and groups in the election process and thereby to equalize the relative ability of all citizens to affect the outcome of elections.”); Austin v. Michigan Chamber of Commerce, 494 U.S. 652, 660, 110 S.Ct. 1391, 1397, 108 L.Ed.2d 652 (1990) (regulation said to target “corrosive and distorting effects of immense aggregations of wealth that are accumulated with the help of the corporate form and that have little or no correlation to

This methodology has come to replace the distinction between speech and conduct regulations originally articulated in United States v. O'Brien, 391 U.S. 367, 375, 88 S.Ct. 1673, 1678, 20 L.Ed.2d 672 (1968). See John Hart Ely, "Flag Desecration: A Case Study in the Roles of Categorization and Balancing in First Amendment Analysis", 88 Harv.L.Rev. 1482, 1496 (1975) (noting that the O'Brien Court itself adopts purpose test later in its opinion, "abandoning] its earlier suggestion that the constitutional answer can be found by examining O’Brien’s act”).
