Why Marco Rubio is insisting that his massive tax cuts will pay for themselves, explained

Conservatives hate taxes, they dislike deficits, and they’re scared of spending cuts. Dynamic scoring is the answer.

The basic idea here is that massive tax cuts boost growth so much that they pay for themselves, and so there’s no actual trade-off between lower taxes and balanced budgets.

.. As Jonathan Chait wrote, the skeptical reception Rubio’s plan got among many on the right spoke to a problem almost without precedent in the modern GOP: Rubio had designed a tax cut “so gargantuan that nobody in the party actually believes it.”

.. While Rubio gives some lip service to deficit reduction — he later tells Harwood that balancing the budget will require entitlement reform, not just tax reform — he clearly cares a lot more about the tax cuts than about the deficit reduction, just as Bush did.
