Here is another article I came across at Pajamas Media: http://pjmedia.com/blog/perry-the-only-credible-choice-for-latino-conservatives/?singlepage=true
This article addresses Romney vs Perry but I also believe Herman Cain hurt himself with Latinos with his "joke" about the electric fence.
Texas in-state tuition for illegal immigrants makes sense to me. It obviously made sense to the Texas legislature. Perry has an A+ rating from Numbers USA for border security.
