Interesting that you folks think everyone who lives in Washington, DC has something to do with the government or politics. There actually are lots of private citizens there.
I will not answer caller unknown name unless I personally recognize the number as belonging to someone I definitely know. I keep getting calls from this number 2-5 times per DAY!
This "unknown" caller from this number called today, asked another family member that answered the phone for me by name. When I got on the line about 20 seconds later, they simply hung up.
After a few months of reprieve I got a call today from this number. Like other unknown numbers on my caller ID if I'm home I now just pick up the phone and set it down without saying anything. After several minutes I hang up. This has worked with other numbers not calling again at least for several weeks.
