In this instance they're not? The DSA spokesperson (who I would say is broadly right on the overall chapter attitude) is tacitly saying that putting resources into forcing the vote is dumb, there's better stuff chapters are already doing. A relatively small amount of DSA time and money goes into electoral stuff overall tbh and the majority of what is done is focused on local races. That stuff is more important than the congress seats (which are still important though so they get some resources, and are also one of the best recruitment strategies for bringing in new members, and other logistical benefits like constructing new power networks, but these cannot be done on the timeframe of a push for force the vote that would be disruptive to ongoing campaigns).
