That pic is a photoshop created by ‘Registered’. They were both at that rally that day but did not stand/speak at the podium together. That photoshop pic has been used to discredit the right for years.
There are pics of them both sitting in the audience at that rally a couple rows apart but have been scrubbed. There are probably Freepers who still have those pics.
The other pics are still floating around as well. I don’t know that the photoshopped version has been used to “discredit” the right. It feels more like “twisting the knife” to me. Everytime it is used you get howls from the left, but then they have to admit that Kerry and Hanoi Jane were both at that event and together at many others. At least it is a decent photoshop unlike the ones put out by Obama of him and his grandparents, his fake BC, and etc, etc, etc... Most of Obama’s official narrative is backed with poorly done forgeries.
