You might to educate them about Obamacare and how it takes $500 billion from Medicare over ten years and uses it to supply medical care for others, and about the unavoidable rationing of Obamacare, and how "death panels" will result in seniors receiving even less care.
They're not buying it. "Partisan politics" they claim and they think the term "death panel" is the most ridiculous example of fear-mongering they've ever heard of.
All they know is that their medical coverage is paid for now and they're going to trust the Democrats to keep it that way.
