Republicans “conservative principles” call for empowering “local” solutions, exercising “local” problem-solving and stimulating “local” innovation, the states as “laboratories” for policy experiments.
To do this, Trump/Republicans could provide incentives by allowing deductions for State and local taxes paid.
Wait! We already do that! Our current tax code provides for off-setting a portion of State and local taxes to do just that!
Those are the incentives Trump/Republicans want to kill off so they can give tax breaks to corporations and the most wealthy.
When padding the wallets of the most wealthy conflicts with applying “conservative principles”, we see who wins.
