They called once Saturday morning (7/28) and just now (5 P.M. on 7/29).  Caller ID says "Unknown Name."  They left no message.  No surprise that it's political polling, as indicated by others on here.

Got a call on Friday 7/27 and I picked up and it was a robo call wanting to ask me about whether Oregon was on the right track or not. Choices were #1 or #2. I tried every other number to try to get removed and was greeted with a 'you chose an invalid answer' sort of response.
Got another call just now (Sat 7/28, 2:30) and tried to call back with my number blocked. No one answered.

I just got a call from this number about an hour ago.  Same MO as you guys. No message. Maybe some sort of automatic calling or polling system.

calls every few months from this number. I have never gotten a message and when answered no one is there. they seem to come in 2's. one during the day then again at night got them yesterday 7/27 and again today 7/28

I have had 2 calls from this number. They do not leave a message.

called twice. left no message.
just says Sherwood on the caller ID

I have gotten calls from this phone number several times.  I have not been near the phone. They do not leave a message.   Only VERY few people even have this number, so I am not pleased to be getting a call that is unidentiftied.  If I ever answer and find out who it is for sure, I will report them to FCC.

Political Republican Poll Call.   This is a Oregon number located in Sherwood, Oregon.  They are very slanted in their opinions and try to scare you.
