I had been a member up until they supported Obamacare, against the wishes of almost all of their membership.
I immediately tore up my card, and sent it back to them cancelling my membership, and joined AMAC, the Association of Mature American Citizens.
I figured AARP must have had some "internal" reason to so strongly support this POS legislation, and now I know why.
They license out their name to independent companies selling "Medigap" insurance, and collect a 4.95% "royalty". This "royalty" brings them in a huge chunk of money, and like most things these days, It's All About The Benjamins.
Please go read the article here on the Political Outcast site. It's very interesting.
