you cannot pass a law that changes the constitution. that requires an ammendment.
until and unless the income tax ammendment is aboliched (which may take years, 2/3 states, etc..) don't expect this pollack to sign onto ANY new tax proposal.
at least mine stays within the confines of the constitution (AFAIK) and would not require an ammendment.
"you cannot pass a law that changes the constitution. that requires an ammendment."
True, but you can put language in the passed law that it will not take effect until the amendment is abolished.
