Thee Campaign Legal Center, Democracy 21 and Public Citizen today filed a friend-of-the-court brief in U.S. District Court for the District of Columbia in Republican Party of Louisiana v. FEC, a case attempting to further undermine campaign contribution limits.
Under one of the key provisions enacted as part of the 2002 McCain-Feingold law and upheld by the U.S. Supreme Court in 2003, state and local parties have limits on how much they can raise for federal election activities. With the help of Citizens United lawyer Jim Bopp, the plaintiffs – the Republican Party of Louisiana and two of its local committees – argue that the First Amendment forbids Congress from limiting the sources and amounts of these contributions.
Update: Here is a Brennan Center brief.
