OCTOBER TERM, 1975 Per Curiam 424 U. S. process and thereby to equalize the relative ability of all citizens to affect the outcome of elections. 6 Second, it is argued, the ceilings may to some extent act as a brake on the skyrocketing cost of political campaigns and thereby serve to open the political system more widely to candidates without access to sources of large amounts of money. It is unnecessary to look beyond the Act's primary purpose-to limit the actuality and appearance of corruption resulting from large individual financial contributions-in order to find a constitutionally sufficient justification for the $1,000 contribution limitation. Under a system of private financing of elections, a candidate lacking immense personal or family wealth must depend on financial contributions from others to provide the resources necessary to conduct a successful campaign. The increasing importance of the communications media and sophisticated mass-mailing and polling operations to effective campaigning make the raising of large sums of money an ever more essential ingredient of an effective candidacy. To the extent that large contributions are given to secure a political quid pro quo from current and potential office holders, the integrity of our system of Contribution limitations alone would not reduce the greater potential voice of affluent persons and well-financed groups, who would remain free to spend unlimited sums directly to promote candidates and policies they favor in an effort to persuade voters. 27 Yet, a ceiling on the size of contributions would affect only indirectly the costs of political campaigns by making it relatively more difficult for candidates to raise large amounts of money. In 1974, for example, 94.9% of the funds raised by candidates for Congress came from contributions of $1,000 or less, see n. 23, supra. Presumably, some or all of the contributions in excess of $1,000 could have been replaced through efforts to raise additional contributions from persons giving less than $1,000. It is the Act's campaign expenditure limitations, § 608 (c), not the contribution limits, that directly address the overall scope of federal election spending. 26
