Paul has been consistent in his attack on counter-terror methods which violate basic human rights. He has also taken a strong anti-war stance in the face of the fact that many Republicans are hawks.
In a campaign speech in Iowa Paul noted that even Nazis after World War II got trials. Now even a U.S. citizen such as Anwar al-Awlaki can be assassinated without any trial, or even being charged. Both Awlaki and also his son a 16 year old were both killed in Obama ordered drone strikes.
Of course, the Obama defenders will simply say that there is a state of hostilities between Al Qaeda and related groups and the U.S. and just as in warfare one can target and kill the enemy without trial. At the same time the Obama administration does not even regard the term "war on terror" as politically correct while employing the notion of hostilities as a means to place any suspected terrorist beyond the reach of any basic legal rights.
Some in the crowd booed Paul as he brought up the drone issue without prompting. However, Paul's position on this matter has been consistent. Many in the American populace are fed up with politicians who pander to them and then go their own merry way after they are elected. Even if people do not like many of Paul's policies they realize that he is different and respect him for that. I have included a You Tube video with Cenk Uygur of the Young Turks which shows even some liberals give him respect. For more see this article.. Establishment Republicans have moved into an Anyone but phase of the campaign.
