Adding to the problem is that the fact that the 'guest post' seems pretty clearly to stem from inter-group Dem politics rather than any disagreement that some actual person has with what Matt said.
Right. There's nothing wrong with disagreements - within members of institutions and between institutions - but this is just 'WAHHH ONE OF YOUR PEOPLE SAID SOMETHING MEAN ABOUT US YOU HAVE TO SAY SOMETHING NICE ABOUT US.' I mean, I have no idea if Third Way contacted Palmieri and complained or not, but in any case this sort of ego-smoothing is really really childish. But it's how the Village works! We are ruled by children.
