Political Action Committees or “PACs” are organizations that pool campaign contributions from various members, and then donate those funds to either promote or attack candidates, ballot initiatives or legislation. PACs are regulated by the Federal Elections Commission or FEC.
The graph below is the current contribution limits for the 2015-2016 Federal Election:
Independent Expenditure Only Committees (IEOCs) or “super PACs” can accept an unlimited amount of contributions and are able to spend an unlimited amount of funds supporting or opposing candidates, campaigns, and parties.
Unlike traditional PACs, super PACs cannot directly contribute or donate to a candidate or political party. Alternatively they may work in parallel with a candidate or party, though campaign finance laws prohibit super PACs from directly coordinating with the candidates or campaigns they support.
