The primary function of a political lobby is to influence legislation and policy decisions by advocating on behalf of specific interests or groups. Lobbyists engage with lawmakers, provide information, and attempt to shape opinions on issues pertinent to their clients. They often represent corporations, non-profits, or advocacy groups, seeking to promote agendas that align with their goals. While lobbying can provide valuable expertise and insights, it raises ethical concerns regarding the potential for undue influence over public policy, making transparency and regulation essential in the lobbying process.
