who is calling from this number?

I got a call from this number just a few minutes ago. It was a guy asking polling type questions about whether I thought Pres. Obama's policies were helping or hurting the economy. Then he went on to ask why I though the way that I did. When I answered him, he said "that's an interesting theory" as if what I said was something he didn't agree with, leading me to believe he was a Republican.

It was a one question Political survey.  They asked me if I believed president Obama's policy's have helped or hurt the economy.  That was it.  I answered, she said thank you and to have a wonderful day.

Called and never said anything. Annoyed that I ran to get the phone only for them not to say anything.

Answered phone....no one there.
