legislators’ email addresses

i’m working with Linton Hale (so please get wordpress version from his input), + am doing a random search as to how many legislators provide an email address . . . not very many, it appears.

do you have any thoughts on this?

also, many offer only contact forms on their websites, so i’m wondering if contacting them via a form still provides collectible email data for Sunlight Foundation + therefore your plugin? my hunch is that it does not.
