@engineer,
Well, relatively little will get done, but the main reason for that is because Mr. Obama frivolously wasted all of his second-term political capital in pointless attacks against the NRA, and now he has nothing left to drive a second-term agenda with.
This means that the only things which will get done are things that the Republicans also want to achieve.
There were Republicans who wanted to pass immigration reform, so that is something that might have been done, but Mr. Obama stomped all over them with his executive orders, so immigration reform is off the agenda now.
There are Republicans who want to pass large trade deals with Asia and Europe. Presuming that Mr. Obama can avoid burning bridges with those Republicans like he did with the immigration reform supporters, he'll likely see those trade deals passed.
