Centrist democratx are learning what life has been like for Republicans since the days of Kennedy and LBJ.The squeaky wheel gets the grease. Within the Democratic Party, the far-left is the squeaky wheel - they squeak a lot and get press coverage, so the Party leaders have to appease them a bit to get them to stop squeaking. Meanwhile, the remaining centrists within the Party don't squeak as much as the far-left, so they don't get greased like the far-left.
Since today's media by and large mirrors the ideological mindset of the far left and hasn't a shred of integrity or principle, those freaks get favorable press no matter what they do. Meanwhile Dem centrists get negatively slanted coverage (especially in misleading headlines), lukewarm approval under only the very best of circumstances, and are generally treated like a leprous uncle who just audibly and wetly farted at the Thanksgiving table.
