I have yet to hear ANYTHING about protests from the Leftstream Media.
I watched to see if there would be any coverage of veterans' protests, especially given Kerry's emphasis of his service while on his water taxi cruise. Of course, like you, I saw zero in the news about the demonstrators. I was sure that there were some protests, but somehow the mainstream media just missed them (as usual). I noted, as well, that the media makes it sound like Kerry's "crewmates" are all 100% supporting him... they might want to check with the Swift Boat Veterans' group on that point.
Rest assured, protesters will have equal time by the time the RNC coverage ends.
