Talk politics.

You keep saying that, but there is no logical progression that says blocking stopgap measures will ensure shutdowns don't happen in the future, unless if the reason for doing so is to intentionally increase the pain of the shutdown to cause the Republicans so much much political damage they would not only break with no concessions, but they wouldn't dare do it in the future. Essentially, Democrats would be hurting people for the benefit of the anti-Republican propaganda it would provide.
