Rasmussen does the breakdown:

Alaska Governor Sarah Palin is the top choice for those Republicans who put national security first and ties Romney for first among voters who list economic issues alone as the priority.

In a perfect world national security conservatives would probably choose Cheney as the 2012 nominee, but he wasn't on the Rasmussen list, and folks shouldn't be terribly surprised that Palin comes out on top in this breakdown. Mitt did wave the white flag on Iraq, and Huckabee isn't exactly a foreign policy titan. National security conservatives mostly went with McCain in '08, and Romney will have to court them aggressively (which to his credit, he is doing) if he wants to gain their support for a run in 2012.
