Trump is not defending the Constitution. He is testing how much of it he can violate before anyone stops him.
He is testing whether a president can wage war without Congress. He is testing whether federal power can be turned into personal power.
He is testing whether dissent can be punished without formally outlawing speech. He is testing whether masked government agents can operate as a secret police force beyond public scrutiny and constitutional accountability.
Libertarians think that they should give up defending freedom because Americans hate liberty, but Libertarians should keep resisting tyranny for selfish reasons.
While the elites control the money, government, and media, the 99% have the numbers.
One Libertarian may not be able to resist being sent to the concentration camps, but one million people might.
