His views represent libertarianism if he believes that the child should not be considered a person under the law until birth. IF he believes that, then his view is consistant with libertarian ideology as any influence by the government would be on behalf of no one and simply oppressive to the woman. Thus, an unnecessary government intrusion.
HOWEVER
If his view is that the child should be considered a person under the law then his view point is completely split from libertarianism. Libertarianism is NOT anarchism, those are two seperate things. Libertarianism allows for government involvement in specific instances, on such thing is for protection of rights being infringed upon by another. In this case, if he believes the child should be considered a person under the law, then its a legitimate libertarian believed function of government for the government to act as a protector of a child whose having a potential major right violated. If his belief in regards to the child falls here, then he is actually completely going 180 degree's against libertarian philosophy. TO say otherwise would be to suggest libertarians are in favor of removing laws that say the state could step in and take your child into protective custody if you attempt to kill them, which would be untrue.
So whether or not his view point can fall in line with libertarian philosophy relies 100% on his own personal view point as to whether or not the child in womb should be legally considered a person under the law or not. If no, then he's in line with his supposed beliefs. If yes, then he's running counter to it.
The third option of course is that he thinks what it should be considered under the law should be a matter of the people since there is no true way to 100% unquestionably declare it one way or another OTHER than opinion and as such that determination should be a state issue, not a federal issue.
