Guns, ammo - stockpile. Dried beans and legumes and white rice stored in a dark and cool place in an airtight container can keep up to 20 years. Medicine and first aid supplies. Blankets, especially heavy duty military crap. Anything related to your skillset that you will bring to the operation (talking about a peacful political campaign of course), also keep in mind that you need to be able to teach the others to learn the basics of what you know so they can assist you if needed - be prepared to learn what they will teach you. Prepare mentally that one day you will have to walk out the door of your home and leave your loved ones behind with the possibility of never seeing them again.
