I recall an adage about a dearth of choosing going hand in hand with begging.... How does that go again?
My parents HAD prescription coverage (my mother had it because she was a retired teacher) but their bills were STILL upwards of $500/month.
So, if you want to make an argument about constitutionality I am willing to consider it. (Of course, I would prefer to push removing other unconstitutional programs first, like NPR.) But I am not willing to concede that this program isn't needed in some fashion or other by a great many elderly.
