I gave him an F because he contended that he'd send men from the government with guns to force Individuals and groups of Individuals to relinquish their right to property.
As you may know, the right to property is an indispensable and principal material support, not only of Man's God-given unalienable rights, but of Man's right to Life and Liberty itself.
His contention that he rejects the indispensable and principal material support for the right to Life and Liberty itself is a patent contention that he rejects the concept of the right to Life and Liberty fully.
Also he wanted a basic universal income funded by involuntary carbon taxes and he contended that he'd consider transferring power from The People to a King.
He said these things under the banner of Liberty, no less.
So basically, screw Gary Johnson and the
stalking horse he rode in on is my view.
