Time to start praying or whatever your wont is.

Three years after the landmark Citizens United decision that dramatically changed campaign finance laws, the Supreme Court announced Tuesday it will take up another campaign finance case challenging how much donors can give to campaigns and committees.

The court will hear McCutcheon v. Federal Election Commission, which deals with the constitutionality of aggregate contribution limits, in October. Shaun McCutcheon, an Alabama resident, contributed a total of $33,088 to 16 different candidates during the 2012 election cycle and thousands more to party committees. He wanted his total contributions for the cycle to total $75,000 to party committees and $54,400 to candidates but was barred from giving at that level by federal aggregate limits.

The Republican National Committee and McCutcheon challenged the FEC’s contribution limits under the First Amendment, saying the $46,200 aggregate limit for candidates and $70,800 limit for committees was “unsupported by any cognizable government interest … at any level of review.”

The U.S. Court of Appeals for the District of Columbia upheld the limits.
