Personally, I think its because its message became diluted. At least here in Portland, it started off strong, in solidarity with the rest of the country. But as the days went on, it became unclear what anyone was actually protesting. Then as the week dragged on, it became less of a protest and more of an opportunity for vagrants to join in and camp. As all that happened, there was less discussion about the protest and more about the giant camp that was building downtown, the drug use, the fighting, etc.

So the message was just never strong and clear enough to cut through the problems that surrounded it.
