The cynical strategy is just that - not to have a budget. That way the Dems can just sit back and demagog the Republicans for making the big decisions balancing a budget demands.
It’s far worse than that. Without “zero based budgeting,” all of the money being spent now will be included in the next years budget as a baseline. That’s one of the main reasons they haven’t been willing to pass a budget. The baseline in the “baseline budgeting” they use keeps growing.
