Abstract: | SUMMARY Interest groups are key players in contemporary campaigns and elections. Along with candidates and political parties, interest groups invest heavily in attempting to influence the outcomes of electoral contests, including presidential races. While scholars have investigated the resource allocation strategies of presidential candidates, little is known about how interest groups distribute resources in presidential campaigns. This study examines spending on political advertising in the 2000 presidential election and compares interest groups' resource allocation decisions to those of the candidates' organizations and the national political parties. The findings reveal that, although interest groups are numerous, disconnected and geographically dispersed, these entities—in the aggregate—adopt allocation strategies similar to those of candidates and parties. |
