I just got a gmail ad for a BCNDP sponsored site that attacks votesmartbc.com - a site that attacks the BCNDP. Now while I did end up reading the BCNDP attack site I also ended up reading votesmartbc for the first time.
I think this ends up being a net loss for the BCNDP. I end up exposed to criticisms of the BCNDP I wouldn't have otherwise seen, and I end up exposed to criticisms of the critics. But I can't vote for or against the critics.
