That's because you can only think in black and white terms that you can't tell that it's not just 'leftist' that would be motivated to vote if the DNC had catered to more progressive policies, but a lot of people on the centre that had also been disillusioned by the political system. We've seen many times that progressive stances gets a lot of support from people of all political spectrum, yet the only thing the DNC can think to do is try to appeal to the right side of the spectrum that would still only vote for a Republican? So ridiculous.

In the meantime, you can continue putting your head in the sand and enjoy watching Harris get less support than Hillary because the 'leftist' are not worth listening to. I'm sure you think if she had slid even more to the right, she would've gotten more support, right?
