But you don't believe that. You already said you don't believe in Sanders and his platform. Just some of it. You have said repeatedly you can vote for someone and not support everything they stand for. So your stated reason for not voting for either is a lie.
If you vote down ballot, are you only voting third party? If not, you are voting for democratic policies and say you support and stand for them. Or does it not work that way when it isn't president?
It's bad enough that this idea that not voting or voting their party means you aren't taking responsibility for either is wrong (That's no how FPTP systems work.), you don't even believe the "any vote means you support them" idea you are using to justify it.
A do believe in the Sanders platform. I don't believe in Joe Biden. It's that simple. For some reason you equate support for policy as unwavering support for a candidate.
A candidate is worthy of a vote based on platform and history of voting and positions. Sanders was consistent in his policy beliefs. And so became the torchbearer.
In essence I and others trusted Sanders to TRY. To actually use the power of the Presidency to try to implement things. And also the power of veto to NOT let things pass.
I and others do not believe Joe Biden will implement anything but Republican lite policies. So why work hard for him. Or even vote for him.
Working down ballot doesn't mean working for every Democrat. Why the hell would I support Pelosi or Joe Manchin? It means working down ballot to primary progressive candidates in and work for them.
Finally it's a lie told by big parties that someone can't vote third party. We can. They don't own the vote. And I've seen far to many elections. Every one is now an "existential threat" so you HAVE to vote for us! Only then can we start to think about policy. In the meantime it's appeal to the right first. For decades.
Sorry but there is now a section of the population tired of the lie as the corporate money flows.
