What is the McCain-Feingold campaign reform act?

The act called the McCain-Feingold campaign reform act is actually the act known as the Bipartisan Campaign Reform Act, meant to change the financing of political campaigns. The major problem that has been found with the BCRA is that because of a difference of definitions between section 527 of the Internal Revenue Code and BCRA on political organizations and political committees "527 Organizations" are now able to spend unlimited soft money.
