If issuance of Concealed Carry Permits is the defining issue for anyone in this race: Bill Gore will be "business as usual". i.e., "don't hold your breath."
For Jim Duffy it will be more accessible, but will ultimately hinge on a personal interview. His decision will be based upon his personal opinion and could be as subjective as how you are dressed. ("May Issue").
Jay LaSuer's stance is if you can legally buy a gun you should be able to legally carry it concealed. ("Shall Issue").
In my opinion, it is starting to look like the conservative vote will be split between LaSuer and Duffy, leaving Gore with a majority.
