they've called 3 times in the last hour. Why would they call a Cdn # to ask about US political views? I think it's obvious they are just going down a list of #'s from all over Canada & the States.
Besides DNC complaints, also make an FCC complaint. Look through the details to see which choice describes your situation best, landline or cell, robocall, live representative, abandoned call, etc.

Make one for each call and/or number they used. There is a field for the exact time, too, that is important for calls after 9pm.
971-208-9960 and 971-208-9963, Same recording both times saying I've been SPECIALLY!! chosen for a political survey and I'll get a trip to Bermuda for participating. I'm in Ontario, Canada so they are not calling only in the US.
