WRONG!
Medicare and Social Security are both entitlement programs. You pay into the system, so you are entitled to the benefits. 

Obamacare didn't cut Medicare benefits for seniors. It increased them. Under the ACA hospitals agreed to a cut of $750 million Medicare payments in exchange for an increase in Medicaid payments. Covering more people with Medicaid meant hospitals wouldn't have to provide as much uncompensated care.

Obama care has had zero affect on my health care coverage. I got to keep my doctor. I got to keep my insurance. The people who whine the most about it, aren't even affected by it. I'll bet you're one of them.
