@ Bart :

Of course being a volunteer doesn't make anyone immune to criticism, but there is a difference between criticism and belittling people by calling them plebs. I've never canvassed but if I did, I doubt I would have the time to stand at the door and debte issues if I was ever to have a hope of delivering party literature.

@ Paul M.
I get my information from reading party policy documents, tv/radio/newspapers, candidate websites etc. and make my own decision. I would find it wholly unproductive to start a debate at the doorstep with a party activist (even a well informed one) who is obviously going to put a positive spin on things anyway.
