Andrew Cuomo (Governor of New York) is planning on suing over the 2018 tax plan, claiming it to be unconstitutional: https://www.usatoday.com/story/news/nation-now/2018/01/03/cuomo-new-york-sue-over-federal-tax-law/1001655001/
It sounds like the biggest complaint he has is the changes to the state and local tax deductions. This affects states like NY with high state taxes more than other states and might cause high earning people to leave the state.
Given that constitutionally congress has the power to levy taxes, does the claim that it is unconstitutional to not have a state and local tax deduction have any merit at all?
