Has been constantly calling multiple times a day.

A call to the number gives no rings, just dead quiet, then disconnects (hangs up on me!)

Probably another Scott Walker Republican push poll, can't confirm, though.

Received a call from this number twice in the last 2 hours.  Didn't answer and no message left.

3 calls in as many hours, no message left

got call.  didn't answer.  no VM left.  called number and was disconnected.

3 calls within about 3 hours. No message left. Also called the number and it had no rings and I was disconnected.
