Actually, PACs, Super PACs, Citizens United, and any other similar ones must be made illegal for true election reform. And only those who can vote for the person or referendum/initiative can make total campaign contributions of $5K during any one election cycle. Corporations can not make matching donations because they can vote. By limiting the total amount one can give, it gets big money out of elections and limits corruption. By only letting those who can vote for the candidates to contribute their campaigns it keeps out foreigners, foreign governments, and corporations.
