The one thing that people worry about the most -- that Trump would try to privatize Social Security -- is out of the question. He's signaled that he opposes that. Few Congressional Republicans would have the heart for such a fight. Even Donald Trump can recognize that this is a fight he would lose badly. I wish he would try but he won't.
While there are many, many frightening things that could happen at Social Security in a year or two or four, the only immediate threat is to the agency's operating budget. We're on a continuing resolution now which runs out in December, if I remember correctly. I expect that will get rolled over until the Spring. Over the past six years the House GOP has been demanding greater and greater cuts for all agencies, including Social Security, and damn the consequences. However, it's been noticeable in the past that the Congressional GOP has always seemed far more interested in budget austerity when there was a Democratic President than when there was a Republican President, not that Social Security fared well under President George W. Bush. We are at the point that the news media can already report on horrendous backlogs at Social Security, if they choose to. Do Republicans want to risk bad media coverage on this? Do they even recognize or care about that risk when they've just been able to elect a President who's been accused of, among other things, sexually abusing more than a dozen women?
