Things that will be Lost

Roe v. Wade.  Obamacare.  Medicare (will be replaced by a voucher program.)  Social Security (depends on Republicans other than Donald.)  Freedom of Speech.  Privacy (there is a rumor that the NSA will be given free reign to spy on all Americans when Donald takes office.)  Regulations to curb pollution from coal-fired power plants.  Dodd-Frank financial regulations.  The estate tax (applies to 5,300 of the richest Americans); the Alternative Minimum Tax.  The Paris Climate Change Agreement (this will be harder to ditch than other things); payments to the United Nation’s climate fund.  The Education Department.  The Environmental Protection Agency. The North American Free Trade Agreement; the Trans-Pacific Partnership.  Deferred Action for Childhood Arrivals (protects undocumented/illegal immigrants who arrived here as children); deferred action for parents of Americans and lawful permanent residents (currently blocked by a 4-4 tie in the Supreme Court.)  See also this article in the New York Times.
