Colorado constitution
Article XXVIII
Section 1

The people of the state of Colorado hereby find and declare that large campaign contributions to political candidates create the potential for corruption and the appearance of corruption; that large campaign contributions made to influence election outcomes allow wealthy individuals, corporations, and special interest groups to exercise a disproportionate level of influence over the political process; that the rising costs of campaigning for political office prevent qualified citizens from running for political office; that because of the use of early voting in Colorado timely notice of independent expenditures is essential for informing the electorate; that in recent years the advent of significant spending on electioneering communications, as defined herein, has frustrated the purpose of existing campaign finance requirements; that independent research has demonstrated that the vast majority of televised electioneering communications goes beyond issue discussion to express electoral advocacy; that political contributions from corporate treasuries are not an indication of popular support for the corporation's political ideas and can unfairly influence the outcome of Colorado elections; and that the interests of the public are best served by limiting campaign contributions, establishing campaign spending limits, providing for full and timely disclosure of campaign contributions, independent expenditures, and funding of electioneering communications, and strong enforcement of campaign finance requirements.
