John Bolton, Herman Cain and Oliver North are the latest political names coming into Pittsburgh for the NRA national convention at the end of the month.

Probable presidential nominee Rick Santorum will be back in town too, as well as Pat Toomey and Jason Altmire. Mike Huckabee and Newt Gingrich's appearances were already announced, meaning the convention is so far getting a few big 2012 names but by no means all of them. (Tim Pawlenty will be in a week later for the county GOP's spring dinner.)

UPDATE: Joe Manchin is a late addition, and not noted in press release below.
