CNN today is not "somewhat centrist" unless your only bar is MSNBC. Over the past half decade CNN has veered into full blown left wing activism.
Even that I don’t think should really be thought of as a single axis - though they’re few enough now, there’s reactionaries who see capitalism as the source of all modern ills beginning with a very old ideological tradition that would look down just as much on communism.
Debatable, but even if true, its corporate capitalist economic stance would have it somewhere between the center and center-right, definitely no further left, the economic axis being the main determinant of left-right position.
