That would take a constitutional amendment, and I think the chances of that happening are next to zero.
Rubio is right to advise that, with any flat-tax, Republicans should press for a supermajority-vote requirement in the House and Senate to raise the rate.
“That would take a constitutional amendment, and I think the chances of that happening are next to zero.”
Correct. And with the progressive GOPe intact a super majority vote would easily be accomplished anyway to RAISE taxes, whether a Democrat majority or Republican majority in Congress.
To bring any of these tax systems on line would take three or four consecutive non-establishment type presidencies and incredible cooperation in a Congress that is in serious need of a purge.
