It doesn't make any difference whether the member was a Democrat or Republican. I'd say the attorney probably was trying to harass, or at least tie up a phone line to his Congressman's office.

Anyone who knows much about Congress knows that the staffers basically record "for" or "against" when constituents call. Even if staffers had the time to engage in a debate on the content of a particular bill, that information would never get to the Congressman. It would still be recorded as a for or against, so the member would have an idea of the feelings of his constituents.

For the blogger to make more of the incident than this is somewhere between stupid and laughable. It only demonstrates an intent to induce a partisan response...as was posting the link here.
