The Democrats can not pass any new laws, since the Republicans hold the House. So the only power they have is that of the president. However Trump can reverse a lot of that as soon as he gets into office. However in foreign policy that is often not the case. For example Ukraine is not going to return US weapons, just because Trump got elected. Also those things are often more important.
