I think that is what is going to happen.
I see the rating agencies starting to flex their muscle and tell what they think is going to happen.
I also think that California is headed for a significant cash flow problem that is going to require the borrowing of short term money to keep things in government going.
To get that short term money, the Legislature is going to have to agree to act fiscally responsible in ways that no Democrat would want to act. That in turn is likely (in my opinion) to cause a significant reaction within the ranks of the populace that views themselves as Democrats and is about to be "betrayed" (in their view) by their elected officials.
