The U.S. Supreme Court today issued its opinion  in 
McCutcheon v. FEC  striking down the current aggregate contribution limit on political contributions.  

The individual aggregate two-year contribution limit had been $48,600 for giving to federal candidates, and $74,600 for giving to political party committees. See FEC brochure , The Biennial Contribution Limit.  

The opinion did not change the individual contribution limit of giving $2,600 to a federal candidate, per election.
