It's really interesting that the two most immigration friendly candidates, Bush and Rubio, do a lot better in the south than elsewhere. I really don't think it's solely cause they're based in Florida. Rubio did really well in a South Carolina poll and now Bush is crushing the competition in Mississippi. Could it be that being the hub for slavery has opened up southern whites' minds when it comes to immigration, being it legal or illegal?
Don't know much about Mississippi, but immigration really isn't that much of an issue here in South Carolina among Republicans. There's not a lot of Hispanics moving in here, as compared to other areas and if there was, to be blunt, they usually take jobs that were done by blacks.
That's another reason why Lindsey Graham is able to 'deviate' like he does on the issue.
EDIT: I found a graphic on FAIR that shows immigration isn't heavy in either SC or MS.
