Really, it's the only explanation: high. From "taxpayer-owned airways" (nope -- gummint-regulated and using largely privately-owned infrastructure at both ends, at least here in the States*) to "...for years wildly conservative voices at places like CBS, NBC, and ABC Sunday talk shows consistently overwhelm progressive voices." Riiight. This would be at the networks whose newsies compete to tongue-shine the current President's shoes, just as they did throughout his campaign. Okay then.
High. At least he's not trying to drive anything other than public opinion.
* Also, I'm pretty sure an "airway" is a preferred route on a pilot's map or the thing the paramedic uses so you can breathe despite having a constricted windpipe. "Airwaves," maybe, except they work in a vacuum, too. Like, oh, I dunno the one inside some writer's heads.
