Gary Johnson: Trump's a pussy

[Minimalist]

Why?  Because it falls more heavily on the poor than the rich?  Because that is what a consumption tax does.

Anyway, here is the Libertarian Platform section:

2.4 Government Finance and Spending

All persons are entitled to keep the fruits of their labor. We call for the repeal of the income tax, the abolishment of the Internal Revenue Service and all federal programs and services not required under the U.S. Constitution. We oppose any legal requirements forcing employers to serve as tax collectors. Government should not incur debt, which burdens future generations without their consent. We support the passage of a “Balanced Budget Amendment” to the U.S. Constitution, provided that the budget is balanced exclusively by cutting expenditures, and not by raising taxes.

You see something about a consumption tax?  I don't.
