Who called from 7406168007

I've received 2 calls from this number in the past few days. No message left either time. I'm guessing that it might be some type of poll or something since there's an election this coming Tuesday. ?

Got 2 calls in the last 2 days left no message

Been getting calls yesterday (11-1-2013) and today from this number (11-2-2013).

Began getting calls from this number this week.  I simply pickup the receiver then slam it down, which deters them for a day at least ...  irritating [***].

Get call ever so often from this # They never say anything and neither do I...It's a mutual admiration society.
