That is a great story by CNN!
No, its not. All it is, is the factual reporting of some poll results. And even then they break them down by politicial affiliations.
The closest thing to great about this CNN story is that A) they ran it at all, and B) that they did not explore any possible reasoning of why support for gun control was down, and how that was a bad thing in their view.
One relatively unbiased story from CNN does not mean a shift in their attitude, or their consistant bias.
