My track record on predictions isn't good but I'll go ahead anyway knowing that my readers can respond with their own predictions.
First, nothing will happen to Social Security's retirement and survivor benefits. Nothing can possibly touch them either now or in the future.
Second, Carolyn Colvin won't be confirmed as Commissioner. Senate Democrats will try to confirm judges mostly in the lame duck session. There's no urgency to the Colvin nomination for Democrats since she remains on as Acting Commissioner until a new Commissioner is confirmed.
Third, Republicans will hold more hearings trying to expose waste, fraud and abuse in Social Security's disability programs. I don't think they're going to find much to expose. There are many claims and many claimants so there's always something but I don't think there's anything major out there. House Republicans have been imploring Social Security's Inspector General for the last four years to please, please find something juicy. You can make your own judgment but I don't think what has been found amounts to much and I doubt there's much more to find. The low hanging fruit has already been plucked.
Fourth, House Republicans will try to draft some legislation to deal with the possible exhaustion of the Disability Trust Fund but I don't think their heart will be in it. Cutting Social Security isn't popular, even when you're talking about disability benefits. They also have a technical problem. Republicans with real knowledge and experience with Social Security benefits are almost nonexistent. My guess is that if they can possibly delay this to 2017, they will and I think they can delay it so that the next Congress will have to deal with it. Nevertheless, pressure will remain on the Social Security Administration to do something to "save" the Disability Trust Fund so I expect some harsh regulatory proposals to try to propitiate the Republicans. That's pointless since Congressional Republicans don't want to be propitiated but the agency never learns.
Fifth, I have no idea what sort of operating budget the agency will get. Probably, it won't be significantly higher any time soon but I'm not sure it will be cut. I don't think the GOP wants the blame for poor service at Social Security. My impression is that Congressional Republicans would like to hold hearings about poor service at Social Security, much like the hearings on service at the Department of Veterans Affairs, but again they have concern that the blame will be placed on them. The hearings on service at VA have resulted in a sharply higher operating budget for VA. I doubt that result is in the picture for Social Security.
