One of the inspirations we are using as a battle plan is the Indivisible Guide in PDF format. It is a 26-page document, written by former Hill staffers on how the Tea Party organized so effectively.
It is being updated regularly so this link will give you access to the latest version.
The Indivisible group is a volunteer group, but their information has inspired dozens of local Indivisible groups around the country. We are fortunate to live in the Washington, D.C. area, where we can have an impact on emerging issues.
