The three candidates, four if you count the incumbent, Bill Gore, made presentations last fall. Gore was the only one against issuing CCW permits. (You should have heard the lawyers laugh when Gore claimed it was against the law to issue CCWs in California.) LaSuer is good, as is Duffy.
Duffy had problems with Unloaded Open Carry when I spoke with him in January. Jim Duffy had the honesty to admit he would require a face to face interview between the applicant and a representative of the sheriff's department. That is not quite Shall Issue, but is much better than what we have.
I wonder about endorsements for loaded open carry in other counties as well as in San Diego county...and in establishments that serve alcohol. I'll have to ask when I get the chance.
Disclaimer, I don't work for the SD sheriff's department, but I gave a donation to LaSuer.
