In Recent Years, Campaign Financing Organizations (Called Political Action Committees

In recent years, campaign financing organizations (called political action committees, or PACs) formed by party leaders in Congress have had the clear effect of:

A) making the party organizations in Congress more beholden and clearly responsive to interest group donations.
B) strengthening their power with party congressional candidates, due to distribution of campaign funds, while providing interest groups with another avenue for currying favor with the politically powerful.
C) keeping interest groups and existing and possible future members of Congress more focused on party leadership, given the importance of the PACs to both.
D) encouraging incumbents to neglect their constituencies and become more beholden to interest groups.
