Reupping this Slate piece of mine that ran in December, on what the opinion has meant in the last decade:
In 2010, the largest reported individual contributors to federal campaigns in American politics were Robert and Doylene Perry, owners of Perry Homes, who donated about $7.5 million to support Republican and conservative candidates. In 2018, the largest reported contributors were casino magnate Sheldon Adelson and his wife, Miriam, who contributed about $122 million in outside money to support such candidates, representing a 16-fold increase over the Perrys’ 2010 contributions, according to data collected by the Center for Responsive Politics. What explains this dramatic shift in American elections, where the wealthiest Americans get to have even greater influence over who is elected and what policies elected officials pursue? The Supreme Court’s 2010 opinion, Citizens United v. Federal Election Commission.
In 2010, Citizens United held that corporations have a First Amendment right to spend sums independently to support or oppose candidates for office. Looking at the amount of direct corporate spending in elections over the past decade, one might think that Citizens United was a bust. Few for-profit corporations spend money in their own names boosting or dissing candidates. But this case helped to usher in a sea change in American elections, and its influence on the decade that followed is hard to overstate. We’ve seen an explosion of outside, often-undisclosed money in elections, candidates skirting campaign finance rules by having shadow “super PACs,” and dangerous foreign interference in our elections. And that pivotal opinion contains all the tools the Supreme Court needs to get rid of remaining campaign contribution limits.
