We rely on the time ordering of these spending decisions to gain leverage on how they are responding to each other by studying weekly spending of a candidate organization or PAC. We restrict our attention to contests held through Super Tuesday so as only to study decisions to compete in states holding contests before the nomination is essentially determined.
Figure 5 provides further illustration of where candidate organizations and Super PACs spent the most, by presenting comparative spending numbers for key state contests receiving the largest amounts of either candidate or PAC spending.
The Act does, however, allow these entities to set up "separate segregated funds," which have come to be known more commonly as "political action committees" or PACs
. PACs are permitted to contribute to Federal political campaigns, and wide latitude is given to PAC efforts to educate members and involve them in the political process.
