Mr. Tankersley begins with his assertion that politicians defend Medicare and promise not to impact benefits because they want older Americans' votes--which fails to recognize that Medicare has undergone a virtual gutting by Obamacare.
Obamacare did anything BUT leave Medicare and its beneficiaries alone--nor will any other politician leave Medicare alone. It's the one thing the government class agrees on--screw the old.
Medicare has already been changed and there's more to come which Mr. Tankersley would know if he bothered to do any research such as visiting the government's CMS website. You can do this at https://www.google.com/#q=Obamacare+changes+Medicare+2019+and++beyond.
If Mr. Tankersley had bothered to base his hostility on fact rather than opinion, he might have noticed that Obamacare in an effort to finance its expanded entitlement payments to people like--well him, perhaps, who can get the government to pay for their premiums if they finagle their income so they earn up to "only" $94,000 a year, cannibalizes Medicare and will scale it back to save government billions of dollars over the next years, the very years that Boomers become eligible for Medicare in a way that will leave Boomers INSECURE in older age.
