Principle is far more profound than something you wear on a shirt sleave to advertise an issue. Principle usually comes packaged as PRINCIPLES, and the prefix is normally MORAL or ETHICAL (something most don't find in politics).
Principle in politics is to not sacrifice an issue because of FEAR.
Ron and Rand Paul are both great examples of politcal principle. Rand did not vote for Kerry out of fear.
I suggest you begin studying Rand with an open mind and perhaps you may learn something of political principle beyond Ron Paul, who is our foundation, Rand's and all who joined the GOP to materialize Ron Paul's camapaign, to RESTORE THE REPUBLIC.
