Why do some people think that PACs now have more influence over members of Congress and the process of congregational legislation that do individual lobbyists?

Some people believe PACs (Political Action Committees) have more influence over members of Congress because they can mobilize substantial financial resources to support candidates and parties, creating a financial dependency. PACs often represent organized interests that can provide consistent funding and strategic support, which may lead to stronger relationships with lawmakers compared to individual lobbyists. Additionally, the scale and organization of PAC contributions can amplify their voice in the legislative process, often overshadowing the influence of individual lobbyists. This dynamic raises concerns about the prioritization of special interests over public welfare in congressional legislation.
