The Democratic Party is working overtime these days to kill liberalism. There is nothing liberal about Ilhan Omar and, to a large degree, there is nothing liberal about AOC. The Democrats are about to give America a meaningful lesson about the difference between what is "liberal" and what is "leftist".
So you're claiming that AOC and Omar - cheerleaders of The Green New Deal, free public college and Medicare For All - hold "conservative / moderate leftist" positions? I thought the right wing position was that the Green New Deal was pie-in-the-sky hippy-dippy chicken-little nonsense because the world isn't ending in 12 years. Would you classify it as conservative or possibly moderate?
Not sure how you derived that from his post. It is clear to me that AOC's Green New Deal represents a break from liberalism. The GND, if implemented correctly, would directly challenge capitalism. Capitalism is one of the core values of liberalism. So yes, the Sanders/AOC wing of the party is "leftist" and opposed to "liberal." We can only hope that they manage to "kill liberalism," as Fuzzy fears. But they haven't taken over the Democratic Party yet.
