I'll ask the same question i did on the other thread. Why, do disaffected voters have to ...
[show] up during primaries or generals to indicate that moving left will pay anything back.
Why not just poll them, or focus-group them, or use proxies like social media?
You seem to have no problem with the notion of leftist groups communicating preferred policies to Democrat strategists, but then seem to bizarrely assume that the only way to communicate a willingness to vote is to actually vote (for a party you don't agree with).
Tell me... We all go out and vote Democrat. They get into power. How do they now know it wasn't the support for genocide that won them the vote and go even further next time?
