I took the video to be more like "This Snowden guy -- how would you (the media) cover it if I pardoned him? How would you cover it if the pardon also came with some dirt I need?" This type of test will serve to settle his direction without having to completely remember his past positions, or even precisely who Edward Snowden is. This is a bit different than the way we do it -- we expect more statistical power with a saved history of repeated trials. "Floating" has been mentioned here. Perhaps "floating" involves trying two different frames to see how the media covers each, rather than numerous A/B trials for more statistical power.
