Strangely enough, I'm still not sure how you feel. I've upvoted you because I think this 'adds to the conversation' even if I eventually disagree with you.
Demonstrably not...
Your line was "... because Leftists didn’t vote for Hillary Clinton in 2008".
So you would or would not have preferred Clinton in the 2008 general election? Over what? I'm serious. I wasn't paying attention at that time to know how she compared to Obama. By the time I was really watching, she was leagues better than trump, but back in 2008, I was a simple straight-ticket blue voter -- doing my duty, punching my card every two years and feeling like I was helping.
(again my point is aimed at inform. Sell me on your point of view. I don't think we're enemies and there is a silent majority who agree on the end goal but maybe not the path.)
How is today's situation on the shoulders of people who didn't vote for Hillary in 2008's Primary?
I know people who have succumbed to not good enough, and let some terrible people win. This is perhaps more pronounced locally, if you start looking, where a handful of votes is the difference between a socialist or liberal winning over a conservative or fascist.
I think this is only happening because capital does what capital does, and it tries to own the narrative. Berating people because the self-appointed leadership failed them is totally not a thing this community is trying to do. right?
