Alaska Libertarian Platform and Joe Miller:
They support limited constitutional government.  Miller wants legislators to elect US Senators, not citizens.  
They support the Bill of Rights for every individual.  Miller says fine, except for LGBT people and women who choose abortion.
They only strong advocate of private property rights.  Joe Miller agrees, especially if he can continue to hide his Mat-Su property and his Kansas farm subsidies.
Sounds like a match made in heaven.
