An extremely active conservative policy advocacy organization fighting Obamacare has reported only $90,000 for lobbying during the third quarter.
As a 501c4 non-profit organization, Heritage Action for America, provides coordination and communication with "citizens who want to be part of their national dialogue. We speak directly to the American people and help them break through the establishment in Washington." The organization was started in 2010 because its sister organization, the Heritage Foundation, as a 501c3 organization, could not back specific legislation.
In August 2013, Heritage Action pushed a large campaign to link dismantling Obamacare with raising the federal debt limit and avoiding the government shutdown. The group sponsored meetings around the country to rally people to pressure their representatives (including Republicans) to defund Obamacare.
Grassroots lobbying refers to attempts to influence legislation by attempting to affect the opinion of the public with respect to the legislation and encouraging the audience to take action with respect to the legislation. It also includes calls to action, such as, influencing a recipient of the communication to contact a legislator or staffer; providing the address or telephone number of a legislator; or providing a petition, tear-off postcard, etc. addressed to a legislator.
