Bundling
The practice of collecting multiple individual campaign contributions and delivering them together to a candidate, amplifying the bundler's influence and access.
Understanding Bundling
Bundling is the process by which an individual -- often a lobbyist, business executive, or political fundraiser -- solicits campaign contributions from multiple people and aggregates ("bundles") them for delivery to a candidate's campaign. While each individual contribution must fall within legal limits, a bundler who delivers $100,000 or more in combined contributions gains significant influence and access to the candidate. Federal law requires candidates to disclose the identities of registered lobbyists who bundle more than $17,600 (adjusted periodically for inflation) in contributions per reporting period. This disclosure requirement was added by the Honest Leadership and Open Government Act of 2007.
However, bundling by non-lobbyists is not subject to the same disclosure requirements, creating a significant gap in transparency. Bundling is a central feature of the Washington influence economy. Lobbyists who are effective bundlers often gain enhanced access to elected officials, including invitations to private events, meetings, and policy discussions. The intersection of bundling and lobbying creates a feedback loop: lobbyists raise money for candidates, then contact those officials about legislation on behalf of their clients.
Both parties and candidates have established formal bundler programs that recognize and reward top fundraisers with titles and access privileges.
