Yes, knocking doors is still a thing. I've interviewed 100's of successful politicans and unfortunately they all same the same thing. Knocking on doors matters. While I would prefer the world to text or call me, most people wont get exposed to the capaign without knocking on doors. I could cold call, text blast, and send countless mailers, but it is not as effective as knocking on a door. Knocking doors is fun, and a great way to get to know your neighbors!
