They think we are stupid with no memory.
When, ever, has a promised “spending cut” ever happened?
Raising the debt limit has an immediate effect. Raising taxes is done by statute. But the budget, per the Constitution, is annual, so a spending cut “ten years from now” has no standing.
I seem to remember when Bush (the Elder) raised taxes, he thought he had negotiated a cap on spending with Congress. Once he signed the tax increase, the Democraps cancelled the spending caps.
