FWIW, and keeping in mind this is only my personal experience with transitioning from lib to ML, I distinctly remember someone online who helped move me further left after Bernie faceplanted and their MO went something like: Being gently understanding of why people are supporting Bernie, but also being plainly a communist and talking about communism in detail, trying to educate people further, explaining why they don’t think Bernie is enough, etc.

I think there were some others I encountered who acted similarly to this too. In other words, there was no impression of condescension or superiority, but of being understanding of how someone would arrive at the position of supporting Bernie, while also being firmly not a soc dem.

The end result was that when Bernie failed, they were still there to pick up the pieces and explain what went wrong and why, with someone who was even more willing to listen to them now. In a way, I guess what I’m describing is what we talk about sometimes with regards to building relationships with people. These do not necessarily have to be close friendships. Even having a relationship of respect as acquaintances is worth something.

During an electoral campaign, true believers in the bougie electoral system can get swept up in the energy of the campaign and stave off doubt in order to push for a win. In the aftermath of a failed campaign, I think it is easier to get through to people, so long as they see you as someone who may be worth listening to.
