Since the Supreme Court’s April 2 McCutcheon ruling, which did away with a cap on how many contributions individuals can make to federal candidates and political parties, 310 political donors have already passed the $123,200 maximum that had been in place for the 2014 midterms, according to Federal Election Commission data provided by the Center for Responsive Politics, a nonpartisan research organization.

In all, these donors contributed $50.2 million to federal candidates and political committees by this summer, including $11.6 million more than would have been allowed before the court decision.

Donor contributions surpassing $123,200

Some donors began to surpass the then-existing $123,200 contribution limit as early as March 2013, more than a year before the McCutcheon ruling.

As the 2014 midterm elections approach, contributions by donors that have already hit the former limit make up an increasing percentage of total campaign contributions by individuals in a given month. This past July, contributions made by donors who had already exceeded the former contribution limit made up 75% of all contributions that month.

Contributions by party

Donors who have already exceeded the pre-McCutcheon cap have favored Republicans. So far, they have given $33.3 million to GOP candidates and party committees and $15.6 million to Democratic ones.
