(403) 254-2398 - This is some kind of political survey in Alberta - March 2012.
Personally, it is not a very good survey.  They ask too many personal questions (such as how are you going to vote - none of your business).  I prefer to answer a survey about issues than to tell anyone how I am going to vote.  
It's easy to ask people how they are going to vote.
What's harder is asking people if they know who you are and what the issues are that you are going to run on.  Why would they do that?  Well, wise residents of a country do not blindly vote for people they know absolutely nothing about.
If I would know which of the politicians initiated the survey, I might be sure NOT to vote for them.
If one of the parties initiated the survey and did not identify that fact, I would be sure NOT to vote for them.
If a candidate initiates a survey, and does not identify that fact, I would be sure NOT to vote fhat candidate.  If I am left wondering which candidate initiated the survey, I would like vote for none of them, or vote for the incumbent because I know who they are.
Most political parties are doing a lousy job of informing residents of their existence as candidates.  The survey was the first I heard of who the candidates are in a provincial election coming up in 2 months.  I just didn't answer the questions, but just let the survey roll on so I could hear what the questions were.  In the end, I had answered nothing, but had learned a lot - like the names of candidates!
More than that - I learned nothing from the survey.
A survey should be entertaining, interesting and informative and make me want to go to the internet to discover more about the candidates.
Most computer generated polls are useless, and results skewed as people will say anything just to give the wrong data to computer.

Called me twice in 10 minutes. No response on the other end when I answered. Called back and left a message telling them to stop calling. So far so good

2 calls from this number within 5 minutes! Must be desperate to get hold of me. Ignored it both times because I let numbers I don't recognize go to voicemail. Another call from them and I'll just block the number. Probably the survey like others have said.

Thanks for the info,  I just received call and like you I didn't answer. (I never do if I don't recognize name or number).  They didn't stay on long enough for my voice mail to kick in.
