Which case solidified the concept that the First Amendment protects corporate political spending, shaping modern campaign finance law?

• A. Citizens United v. FEC (2010)
• B. Buckley v. Valeo (1976)
• C. McConnell v. FEC (2003)
• D. Austin v. Michigan Chamber of Commerce (1990)

Answer: (A)

The key idea here is that money spent to influence elections can be protected speech under the First Amendment when it comes from corporations. Citizens United v. FEC (2010) holds that corporations and unions may spend unlimited sums on independent political communications, such as ads and messages about elections, as long as they do not coordinate with a candidate’s campaign. This ruling is what made possible the rise of Super PACs and reshaped campaign finance by shifting focus from direct contributions to broad, independent spending by powerful entities. It builds on Buckley v. Valeo, which recognized money as speech but allowed some limits, and it marks a shift away from earlier rulings upholding tighter corporate spending restrictions.
