Any non-libertarian will support libertarian principles only so long as their political opponents are in power. Such support will cease once they or their political allies have power when the empowerment of the state (and hence themselves or their allies) will take priority over any previously libertarian positions they held.
The rhetoric of any political group not currently holding sway over the reigns of power will closely match libertarians regardless of their previous rhetoric or current ideological stance.
A person's opposition to state repression grows with the level of state repression they are experiencing. A person with authority over state repression will not repress themselves and hence have little or no opposition to the state repression of others.
No person is an absolute libertarian. Any person will support the repression of others in some circumstances. The ideology that determines which circumstances differentiate most political groups and are the primary guage of libertarianism.
Goe, will throw in some linkage later.
