Listen, I find the far left annoying, entitled and condescending at times but I just don't buy this hit piece narrative of "they cost us seats". It just reeks of lazy finger pointing for having ran piss poor "orange man bad" campaigns that offered the people nothing of substance other than being the lesser of two choices. Yes, perhaps the messaging hurt "sensibilities", and the old guard may have a point, but from where I'm sitting it's just them trying to save their own hide by relying on people's preconceived biases and preference of scapegoating the uppity loudmouth lefties.
I remain open to the notion mind you, but all I'm seeing is "establishment so-and-so said so, so it must be true" without numbers to back up their roasting.
Sorry I did not mean to imply that it was the main reason the Dems lost seats in the house. I tried to steer away from the argument more towards the Dems missed out on a great opportunity to run with a reform message and bring in both sides and actually gain. Losing seats versus gaining partially is the because the Dems allowed a minority to monopolize the issue and let the media run with it
