I believe it is a Political site since it is coming from Washington DC.   NOW BLOCKED!

I just anonymously called this number back.  IT IS A POLITICAL SURVEY. They also do marketing surveys.  Message said if you want your number taken off their system, PRESS 9.    I did, now lets see if they try calling back.

Caller ID indicated Washington DC.
If it's from DC, it can't be good, but they did leave a message asking if I was registered to vote.  The number and message was deleted.

A call from what is most likely a CRIMINAL ORGANIZATION harassing the public.  Reported to FTC for prosecution.  suggest any other victims do likewise
