Supreme Court Enables Attack Ads
The Supreme Court strikes down parts of the Federal Election Campaign Act (Buckley v Valeo) ruling that individuals may spend (but not contribute) unlimited money on political issues as an exercise in free speech. The ruling also establishes the principle that TV and radio ads that avoid express advocacy of a candidate are not subject to regulation, freeing independent groups to air issue ads attacking or promoting a candidate as long as they avoid hortatory language such as "elect" and "defeat."
The Rise of "Soft Money"
Congress amends FECA to create the soft money loophole, allowing corporations, unions and the wealthy to give unlimited sums to national party committees for "party-building" activities.
The Rise of "Super PACs"
Independent groups create political committees under the tax codes Section 527, but tell the Federal Election Commission they're not advocating for or against a specific candidate, thus skirting disclosure requirements. When Congress passes a tighter disclosure mandate in 2005, groups turn themselves into 501(c)4 advocacy organizations, again stretching the rules and further shielding themsevles from having to disclose contributors.
