How to do it:

Print bulk postcards with a patriotic (but generic) message, or thrift them from antique stores. Add your own comments and stamps to get your message through effectively. Consider postcard parties for time-sensitive campaigns, or sit in a coffee shop with materials and a sign welcoming people to sit down and fill out a card. If your goal is to slow down the office instead (e.g. a hostile Senator) use envelopes. Each one has to be screened for contaminants (like anthrax.) Do NOT add anything “cute” like flour. It’ll just scare innocent employees.

Buying stamps also helps the USPS, an independent agency required to run itself like a business. It’s been under attack for years, by Republicans who want to privatize mail service. You can feel good about buying and using stamps. (USPS also sells postcards.)

Here are a few campaigns you can join. They have organized campaigns, templates, instructions and more.

• Postcard to Voters is the biggest (and first?) organized postcard campaign
• Progressive Turn Out Project targets elections
• Project Mail Storm focuses on concentrated bursts of protest activity
