It's a legitimate concern. Moreover, accountability IS very important when the supposed "checks and balances" of a voting system appears increasingly more likely of being neither fully checked NOR fairly balanced.
I sincerely hope that the campaign DOES have a proper strategy to counteract this potential tactic of our, let's face it, "morally disinclined" competition.
The campaign can help us face this danger, and many other like them, if they would make themselves more transparent in ALL aspects, not just financial. The grassroots could adapt and organize campaign efforts with so much more efficiency if we could just communicate/cooperate together better. I suppose there is the security issue though, to be fair.
Ah well, let's just do the best we can.
