On Tuesday, October 8, the second day of the Supreme Court’s new term, the Justices will hear a case about free speech and political donations. In McCutcheon v. Federal Election Commission the law at stake is the aggregate limit on individual campaign donations. Under current campaign finance law, individuals can contribute up to $5,200 to a single candidate (half for a primary and half for the general election). This limit is not directly in dispute. Instead, at issue is a limit on the total of all contributions from a single individual to candidates and to political committees.
