So, we've fallen a little behind in preparing all of the files of candidate disbursements for the data catalog. There are about 600 sets of files in all - one for each House district and one for each Senate candidate, and then groups of those transactions for states and offices. They will be up on the site on May 11.
It looks like we'll have about two-thirds of the Senate first quarter reports keyed in time for the release, so there will be some campaigns for which data from the first three months won't appear next week, but we'll be getting data back each day and updating files as it comes in and is processed.
One note of caution -- while it will be possible to choose "all House" or "all Senate" or "all House and Senate" those files will be large now and much bigger as we move through the cycle - so downloading even zipped files will take quite a while. The files will be updated once each day (overnight).
Thanks for your help as we've put this together. We're looking forward to having this rich set of data available for everyone.
