On the Fence Films, the group that brought us "Dead Meat ," has a four minute film on the role of Marxists on the recent immigration protests earlier this week.
You can find the video here. 
Lots of Che t-shirts.
I did see a very tepid and tiny protest on Monday when I was out in California. Did anyone else go to one in a major city? Was there the kind of influence that On the Fence portrays?
