The file for lobbyist bundling reports is really just the beginning of the story. The next step is to provide the data contained in those reports, and we'll do that in a separate file, at least at the start.
In the meantime (not long, I believe) you can grab the data from individual reports by using the "view/download electronic filings" option from the Campaign Finance Reports and Data Section of the site. Its cumbersome, but there aren't huge numbers of filings yet. The quickest way might be to choose a specific Report Type - e.g. October Quarterly - from the drop down menu toward the bottom of the search page, and also choose "F3L - Rept of Contributions Bundled. . . " from the Form Type menu (yep, we know we need to work on the language we use for this stuff). This would give you the list of all of the filings covering the 3rd quarter of the year that disclose lobbyist bundled contributions.
You can also contact us directly and we can get the data to you.
