Seniors, when you see a so-called non-partisan organization with a name such as the “National Committee to Preserve Social Security and Medicare (NCPSSM),” put your hand on your wallet. You can be pretty sure it is not non-partisan (NCPSSM is a lefty group) and that it is trying to beat you out of some money with its neutral-sounding name. The same goes for a group called the “Partnership for the Future of Medicare” (it's far right wing). Both claim to be giving you good advice and working for you in Washington (send money or get out your credit card).
NCPSSM is an active Democratic Party organization that recently endorsed Democratic Party nominees in multiple upcoming elections. Just donate to your favorite candidate if that's what you want and elminate the middle man. Worse the NCPSSM works tirelessly to repeal the public Part C health plan program and has been doing so almost constantly since the program was made into law.
The right-wing Partnership for the Future of Medicare on the other hand seems as if it were totally created to butt into provider/government bureaucracy battles in favor of providers. There was a flurry of activity when the Part D and Part C rebates were announced back in the late winter of 2014 but the group has kind of dropped off the map since then. There looks like there was a similar pattern of activity/inactivity in 2013 following the group's late 2012 creation.
