Boxer is a California Communist; Carly is a global communist.
I guess I missed the part where she said, "Workers of the world, unite; to each according to his need, from each according to his means; class struggle; abolish private property and private ownership of the means of production." Maybe there are other kinds of communists that I didn't learn about. Otherwise, by using the word indiscriminately, the word is rendered meaningless.
It reminds me of a thread on here a while back when someone called Jon Kyl a RINO.
