It’s not about martial arts or anything, but about reaching people to get them to vote.
Here’s his description because the link preview seems borked:
“Political canvassing or door knocking is an art. Samuel Browning has knocked over 17,000 voter’s doors and pitched thousands of people. This book will teach someone who is not a natural salesperson how to persuade voters. It will also help a first time campaign manager organize their ground game. If you are knocking doors more then once, and are not an expert, this book will definitely increase your skills by teaching you easily learnable techniques.”
If you somehow don’t know who Sam is and how legendary the dude is around here, spend a few years reading our archives.
