Rick and Kay are both busy people, and a lot of what they do is behind the scenes stuff. Fundraisers with big donors. Meetings with their staffs about how to attack certain problems. Only a fraction of what they do is on any kind of public schedule. Texas Watchdog has done the open records requests to get the schedules for Rick (link).
It would be interesting if someone also did this for Kay. I am sure both campaigns are digging into the records of the other side.
