What did voting GOP get you?
Smaller government? No.
Fewer unconstitutional laws? No.
Less government spending? No.
More freedom? No.
Tax reform? No.
A tax cut? Yes. But so miniscule that it is barely noticable. A tax cut that is to be phased in and out. Smoke and mirrors.
All the things that you asked DID NOT happen due to the Libertarian Party. All those things you asked, could have happened with republican control of the congress.
