I am a Christian, and I consider myself a libertarian. However, I am hesitant to affiliate myself with the Libertarian Party on the basis that they seem to refuse to take a stand on abortion. To me, straddling the fence on the issue and turning a blind eye is just as bad as being openly pro-choice. There are many pro-choice Libertarians that I respect as patriotic Americans, but unfortunately could never vote for.
Both the CP and LP have their flaws. The CP seeks to restrict the rights of individuals to view pornography. The LP (IMO) fails to explicitly advocate the protection of the rights of unborn babies to life. In the end, you have to decide for yourself which issue is more important to you. Honestly, I see these 2 issues as the major differences between the two parties. We all know Dr. Paul is a libertarian. I believe libertarians come in all shapes and sizes and I believe each and every one of us could be labeled "libertarian." The reason I believe the CP is a better fit for Dr. Paul is because I believe he would place more importance on the need to end abortion in this country than on the need to make sure pornography continues to exist. That is just my opinion, and I know some of you will disagree with me and that's fine.
