What is the relation between Reconstructionism, Theonomy and Dominionism? It depends on who you ask. According to Marcus Pittman, Reconstructionism is not the same as what he calls "Seven Mountain Dominionism," which is basically the Dominionist position of the NAR.
I have not much interest in the entire Reconstructionist issue, except to say that one must accurately represent the other position and not conflate the two. The two positions are not the same although they are very similar in form.
