I checked around. This phone number is 'called' Tea Party Patriots. Apparently they don't have anything to do with the 'tea party'. The common characteristic among the call recipients is that someone in the household (or the address) might have voted for the Republicans (GOP) in one of the last 2 elections. So this number (group) is being used to harass these people till they get fed up with the Tea Party and stop supporting it.
I can't get more information to find out if this is a Democratic funded scammer or someone doing it on his own funds to try help the Democrats.
Remember the IRS!
Maybe, this is a variant on the same kind of harassment.
If it is really the Tea Party calling, they would wait to talk to you about their cause and ask for your support or at least, for a donation. This number just calls till you want to pull your hair out. No other intent behind it.
I was fortunate today, Tuesday, June 4th, 2013, to find exactly who that telephone number belongs to. It's a fund-raising organization named "Strategic Fundraising", and one can easily find them by simply Googling "Strategic Fundraising". In fact, their Web Site is https://www.strategicfundraising.com, and they are a fund raiser "for not-for-profit and political organizations." Therefore, if you've made any financial contributions to a political organization, you will probably be on their "call list."
