According to earlier news reports that also featured the video, it was taken at a political rally that the parents took the kid to.

They might have thought it would be an "educational experience" although my opinion would be that at her age it's a little like signing up 7 year old kids to play kiddie football so they can "have the experience" of early concussions and a few ripped tendons to prepare them for the early Alzheimers and arthritis characteristic of the grownup pros; but it's possible they just couldn't afford a baby sitter.

Or it could be an outright fraud.

50/50 odds on either.
