The Oxford Practical Ethics blog has two pieces out supporting Dr. Paul. One breaks down Rick Santorum's position on birth control, and the other endorses Dr. Paul's position against the 'war' on terror and on the President's 'authority' to assassinate American citizens. The second post takes a stand against Romney, Santorum, and Gingrich's warmongering. I'm a new user so I can't yet post links, but if you Google the following phrases they'll come up:

Oxford Practical Ethics Rick Santorum
Oxford Practical Ethics Eric Holder
