Communists for Kerry?
Feste is reporting on the "lefts true colors" in other words signs that say "communists for kerry". Blogs for Bush is mentioning the same thing.
I am not a 100% sure on this, but I think it is highly likely that the signs are a farce by Protest Warrior as this post on their message board indicates. Additionally the "Communists for Kerry" posters are in the same style as Protest Warriors usual signs which you can view here. Any doubters that this isn't a parody (although a good one) should take a look at the Communists for Kerry website.
Here are some other blogs that reference these "commies"
