I’m not. I remember it was Lincoln that signed the law, and the tax was what expired in 1872. The Supreme Court went back and forth on income tax. But the Sixteenth Amendment was ratified in February 2013, abd Wilson wasn’t sworn in until March 4th, 2013, so, as much as we want, we can’t really blame that on him, including the expansion of the IRS, can we?
Aside from the dubious “ratification” of the amendment in question, Wilson did campaign on “tariff reform”, that being the primary method of funding the federal government until the amendment’s advent (enforcement). And the amendment removed apportionment with respect to income tax and established its permanency.
Wilson signed the Revenue Act of 1913, which permanently established the income tax.
I don’t want to take blame away from prior “progressives” such as Taft, mind you; he bears a large part.
