In the hands of the FEC. Now that is comforting. NOT!! The FEC is another arm of the liberals.
On the Congressional side, Senators McCain and Feingold, and their House counterparts, Representatives Shays and Meehan, lacking any meaningful way to exert legislative oversight (and probably lacking a majority to do so), decided to invoke the third branch, and so went to courts and sued. A judge, not appointed for her expertise in campaign finance or the internet, held that the FEC was mistaken.
