In what amounts to an independent expenditure on behalf of the other Presidential candidates, CNN decided to hit Marco Rubio for the high crime of having a stump speech.
If you were waiting for the video to end with "I'm (insert Rubio opponent here) and I approve this message," you were disappointed.
The intent of the piece is to leave the viewer with the impression that Rubio is a big fat phony.
I don't know if Rubio is a phony or not. However, every candidate gives virtually the same carefully crafted, poll tested speech at each location they visit on the campaign trail. Not only is this not news, it's electioneering on the part of CNN.
The only explanation seems to be that there's a producer on the show who just cannot abide a Rubio V Democrat general election.
