From a Democratic Hill staffer:
We're on the right side of this campaign--count this office as a big Obama supporter--but OFA gets no points with Congressional allies for the logistics of their maiden voyage. They wasted hundreds of thousands of pieces of paper in a show of force, and then when they brought us these stacks they didn't include email or street addresses--just a typed name, city and zip code--which sure looks like a deliberate attempt to horde DNC/OFA data. (Recall that Tom Harkin's handwritten form had lines for email and street address.) If I were a Dem voting against the president's budget, I'd be doubly pissed.
In contrast, even MoveOn has the courtesy to let us download an Excel file from their site, and it hasn't been scrubbed of relevant info.
