For most issues at the Capitol, having a lobbyist is a successful strategy. But it's the grassroots advocacy that can make or break any deal at the legislature.
The best lobbyists coordinate a grassroots advocacy campaign to supplement their efforts. Even issues and organizations that have no lobbyist are successful with a campaign of citizen advocacy.
Citizen advocacy can be an intimidating thought for the citizens involved. But it shouldn't be. Legislators are elected to represent the best interests of their citizens, so it is important for them to hear from their constituents. Arm yourself with a knowledge of the process – the Oregon legislative website is an excellent resource.
