Today at 5:19pm EST Organizing for America/DNC auto-dialed me and left a recorded message encouraging me to go to one of the events.
I dialed back at 5:23pm EST and left a message requesting that they do not call me again (name and phone number were left) as it would be "a waste of their money".
I know that political groups are exempt from the Do-Not-Call list but I can't imagine any political group would be foolish enough to continue to harass someone but who knows. I'll keep you updated.
For anyone who wants to know, the number I dialed was 1-866-495-2004.
