Interest Groups vs. Political Parties

The fundamental goal of interest groups in the political process is to influence public policy. Where as the fundamental goal of political parties is to gain majority in the government and therefor gain control. Interest groups support the fundamental goal of political parties by contributing to political campaigns and gaining support for candidates. Contributing money to campaigns helps interest groups achieve their ultimate goal of influencing public policy because if the candidate wins they may feel indebted to the interest group and make decisions that benefit them. Or at least get them in contact with policy makers.
