Interest groups engage in political lobbying through various strategies aimed at influencing decision-makers. They often conduct research, organize campaigns, and mobilize grassroots support to advocate for specific policies or interests. Lobbyists may meet with public officials, provide information, and testify at hearings to raise awareness of their causes. Additionally, funding political campaigns is a common tactic to gain access and sway politicians. Through these efforts, interest groups seek to shape legislation and public policy outcomes that align with their goals.
