Whow does the combined federal campaign act of 1971 regulate pacs

As early as 1905, President Theodore Roosevelt recognized the need for campaign finance reform and called for legislation to ban corporate contributions for political purposes. In response, Congress enacted several statutes between 1907 and 1966 which, taken together, sought to:

Limit the disproportionate influence of wealthy individuals and special interest groups on the outcome of federal elections;Regulate spending in campaigns for federal office; andDeter abuses by mandating public disclosure of campaign finances.

In 1971, Congress consolidated its earlier reform efforts in the Federal Election Campaign Act (FECA), instituting more stringent disclosure requirements for federal candidates, political parties and political action committees (PACs). Still, without a central administrative authority, the campaign finance laws were difficult to enforce.

Following reports of serious financial abuses in the 1972 Presidential campaign, Congress amended the FECA in 1974 to set limits on contributions by individuals, political parties and PACs. The 1974 amendments also established an independent agency, the Federal Election Commission (FEC) to enforce the law, facilitate disclosure and administer the public funding program. Congress made further amendments to the FECA in 1976 following a constitutional challenge in the Supreme Court case Buckley v. Valeo; major amendments were also made in 1979 to streamline the disclosure process and expand the role of political parties.

The next set of major amendments came in the form of the Bipartisan Campaign Reform Act of 2002 (BCRA). Among other things, the BCRA banned national parties from raising or spending nonfederal funds (often called "soft money"), restricted so-called issue ads, increased the contribution limits and indexed certain limits for inflation.

Public funding of federal elections originally proposed by President Roosevelt in 1907 began to take shape in 1971 when Congress set up the income tax checkoff to provide for the financing of Presidential general election campaigns and national party conventions. Amendments to the Internal Revenue Code in 1974 established the matching fund program for Presidential primary campaigns.

The FEC opened its doors in 1975 and administered the first publicly funded Presidential election in 1976. 

Hope this helps.

Although the U.S. had not yet entered World War II, the Atlantic Charter showed its support for Great Britain, since this is all the United States could do at the time because the nation was still very isolationist.
