I don't think it has anything to do with the Democratic Party.  I've had at least 10 calls from this number in the last week, and I'm on the Do Not Call list.  It's a sales or marketing call...it may be coming from Puritan Pride Vitamins, but I'm not sure.   I don't know how to block it, but I've identified it as SOLICITOR on my contact list and I simply don't answer it.  Hopefully, it will soon go away.

As a registered Democrat, I've given time and $$ to the party. THAT ENDS TODAY!
I am sick and tired of robocall after robocall, 3 times in a row from this number in particular, several days in a row. They never leave a message and continue to call to the point of extreme harassment. I was on your side in 2000, 2004, 2008. Why wouldn't you harass the other parties -- why continually harass someone who was already voting the Democratic ticket? Is this what happens when I donate to the party? That I can expect to be barraged by endless nuisance calls. Instead of earning my vote, you have officially lost it. You can't be allowed to continue to terrorize people in their own homes.

I have received 4 calls from this number today.  Multiple times other days.  I am on the do not call list.

I called them back...
"You have been contacted for marketing research or a sales call."
Um... six of one and 6 of the other as far as I am concerned.
Garbage by any other name still stinks.

I signed up for the Publisher's Clearing House drawing and I had to give my telephone number. After that I started getting one to two call from the number every night.  I use Advanced Call Blocker on my Android cell phone and it blocks this number.

I have received two calls, one each evening - the phone rings once, maybe twice, and they hang up.  I'm on the Do Not Call Registry also.  Caller ID just says "Unknown Name".

called twice tonight, no message
