And with good reason. Until the shut down is over there is a bigger fudge factor in economic numbers than is usually the case.
RBG had two of five lung lobes removed, which will shorten her life a lot even if she stays cancer free and reduce her ability to do her job. So she will leave the court sooner rather than later. Riots will disrupt business in DC while her successor is going through confirmation and that will be a mini shutdown.
If Trump promotes the private funding of the wall that too will lead to riots. If congress is too busy rioting to do their job a lot of things can spin out of control.
