Iowa Democrat Ravi Patel had to carefully adjust his remarks at a campaign meet and greet yesterday in Dubuque once he realized the event was being recorded. Patel said his staff told him to “be a little careful” because of the tracker’s presence.

What does Ravi Patel have to hide from voters that he has to change his entire speech to reflect the fact that it is being recorded?
