Best to just RTWT, but here you go anyway. I'll just use the cheap expedient of his closing statement, which is like a big old tonic triad ending a song:
"To understand the US political process, one can just look to how these sham debates are organized and how they function. This is the same process that repeats itself endlessly in virtually every other political realm."
Indeed--and I'm not sure anyone could demonstrate that more authoritatively, to a larger audience, than Greenwald. To anyone who thinks they got value out of last night's puppet show: please, read this and check it out for yourself.
The joke is on you. It's always on you.
