I don't think so.  I think the relative success of the right in propagating their narratives has had more to do with owning most of the megaphones for the past half century or so, at least since the invention of television.  And it doesn't hurt that their structure is inherently top-down and authoritarian.

But I think the worm is turning with the rise of the internet and particularly with the rise of forums such as this one.  The Republican party which strutted and talked confidently of an enduring majority just a few short years ago is now in full panic mode.  Even their loudest cheerleaders see only dark clouds on the horizon.  They no longer control the narrative to the extent they did even five years ago.  Looks a little like the internet platypi are eating their corporate media dinosaur eggs and they don't know what to do about it.
