As David Wasserman, the House editor at the Cook Political Report, a non-partisan campaign tip sheet, noted on Twitter on Monday:
Wasserman is a lying sack of **** and a dem propagandist. This fool predicted a D+14 gain. Only off by 26 seats, yet still is cited as some guru.
Indeed. All of these “non-partisan” groups - Cook, 538, etc are all Dem propogandists.
