NAME NAMES PLEASE!!!!!! What “long running practice”??? WHO?? W?? doubt it.....GHW???? Doubt it also....then WHO?? Democrat Presidents??
They said that Truman reenacted his radio addresses for newsreels, and that Reagan stood at the podium after speeches to let photographers take pictures so that the camera sounds wouldn't be a distraction during the speeches. I don't think the story said that Reagan reenacted entering the room, or reread lines of the speeches for the cameras.
And I wouldn't put Truman recording a newsreel of a radio address as the same thing, either. That's just smart for a president to give the address in many forms of media to reach different target audiences.
