Max Bernstein and James Boyce of dotPAC are running a campaign of facebook ads in the districts of the 7 Blue Dog obstructionists , asking people who are constituents to call or leave messages on their Facebook walls.

I asked the dotPAC folks how much it would cost to run these ads effectively, and they said $35 per day per representative.

As someone who looks constantly for effective ways to build pressure within the districts of people who can be awfully hard to target, this is really smart, microtargeted and cost-effective effort.

People around here know that I don’t jump on campaigns lightly — most of the traditional ways that liberals do advocacy are in need of serious re-examination because they just plain don’t work.  But I gave $100 myself to this one.   I think it’s a great idea and recommend it highly.
