This questioner also asks "is anarchism a political position?" However, the previous two answers refer to the first question "is anarchism political," and, I think, the more interesting of the two.
There are many definitions of "politics" that include the dynamic of "power over." For example "use of intrigue or strategy in obtaining any position of power or control." Other definitions seem somewhat circular "the science or art of political government" or "the practice or profession of conducting political affairs." More surprising and somewhat heartening is the following wikipedia definition "Politics is a process by which groups of people make collective decisions." Now I didn't read the entry that carefully, but as I skimmed it, I could clearly tell that whoever authored it isn't an anarchist.
Yet that description "politics is a process by which groups of people make collective decisions" is not a bad one. The basis of the word, "politic" has definitions that include "astute, ingenius; wary, discreet" which I think lend themselves to idea of "power over." But do they have to? I've seen all these qualities exhibited in a positive way in decision-making, as well as a negative way.
So I'm really answering "what is politics" not "is anarchism political" here, but I think the one answer is partially found in the other.
