Maybe that fool Matthews is trying to reposition himself as a real journalist for a jump to another network, since he is no doubt on the chopping block with MSLSD because of his age. The notoriously callous NBC News executives will want to replace him with some younger, more ambiguously-gendered eunuch like Chris Hayes or Rachel Maddcow so they can capture the ever-desirable "youth market" for news (yeah right).
No doubt in the days ahead, Matthews will walk-back his statements to the complexion of damning with faint praise. He'll add a "yeah, but..." or some other crap in order to suck -nether-region to his 'Crat masters.
Matthews is ever pivoting from being a propaganda corps "Good Marxist" to trying to put forth some semblance of "objectivity". It has been his shtick for many years and there is every reason to believe it will continue.
He is a drunk, so whatever value is to be found in his support must be taken with a headache remedy and a bit of the hair-of-the-dog-that-bit-him.
