That video is a textbook example of political propaganda. There is a lot of material out there from his radio show for them to take short clips from the past, of Mr. Franken musing about a certain topic, out of context, and try to paint him a “flip-flopper”.

I know from having listened to Al Franken’s radio show that he would often explain the opposing point of view in addition to explaining his own and I believe that at least one of those quotes was from Mr. Franken doing exactly that.

They could take two sentences from one of his shows and if they did it out of context like this they could easily paint him as a flip flopper because at one point or another he would explain both sides of an issue.
