I don’t know if it was a double, or not. But I didn’t think that the clothes fit the same, and the shoes were different. The clothes on the woman with the little girl were rumpled.
Teresa does not have Hillary’s broad back end, nor her Cankles, nor extreme edema in her feet. The double (whether Teresa or another) does not have the same hair, fingers, ear rings or jewelry.
Regardless who it was, it was not Hillary in the videos.
Now the question, what was the source of the videos? That would reveal what we actually saw.
