The main role of a lobbyist in the political process is to advocate for specific interests, representing organizations, corporations, or groups to influence legislation and government policy. Lobbyists engage with lawmakers and governmental agencies to convey their clients' perspectives, share information, and promote particular legislative goals. They play a crucial role in shaping public policy and often provide expertise or research to support their initiatives. Effective lobbying can lead to favorable outcomes for constituents, while raising concerns about disproportionate influence on the political process.
