Nope, I'm right... you're wrong! (LOL). Though in your 2nd paragraph, I think you're kind of agreeing with me. Let me add a few points of clarification:
1) We tend to forget about NJ's unaffiliated voters, but there are many, many people who are not "political hounds" and thus are likely still not "locked into" a particular party line or ideology. NJ has many such voters:
https://ivn.us/2013/06/18/independents-exceed-party-registration-in-5-states/
(Article is dated 2013, but I've seen more recent stats that were similar).
2) Studies of American voters at-large show that an awful lot of people who DON'T own a gun are actually not at all close-minded about gun ownership. "Three-in-ten American adults say they currently own a gun, and another 11% say they don’t personally own a gun but live with someone who does. Among those who don’t currently own a gun, about half say they could see themselves owning one in the future." http://www.pewsocialtrends.org/2017/06/22/the-demographics-of-gun-ownership/psdt_2017-06-22-guns-01-11/
What does that all mean? That means that, yes, EVEN in states like NJ, there are people that can be swayed with facts about gun ownership. One of my dearest friends is a Bernie-lovin' progressive - but in the middle of her divorce, while moving out into her own place - she suddenly has expressed an interested in shooting with me. Why? Because she's a single woman living alone and she realizes that should would be physically outmatched by an intruder. She's liberal, but she's not stupid! Hell, even the most diehard Progressives like safety and security. It's a basic human desire.
We (the NRA, other 2A groups, the 2A community at-large) are making a strategic error when we let that clown, Gov Murphy, for instance, link that recent Trenton fair shooting to "gun violence". That shooter was an ex-con, a gangbanger, who NEVER should have been out on parole. That shooting, first and foremost, was about our broken criminal justice system. We should be pushing back on that manipulative messaging HARD. The overwhelming percentage of gun crimes are committed by ex-felons, half while they're still on parole. People need to be "taught" that through an education campaign. There are hearts and minds to be won, even in NJ - most of ALL in NJ.
We should also be pushing back hard on his nonsensical "gun trace" stats too. What do they really show? I sat down one day, spent 20 min looking up city populations and crunched the numbers. The troubled cities in this state, with Democratic-controlled majorities, and soft-on-crime approaches (Newark, Paterson, Irvington, Camden and a few others) make up about 8 percent of the state's population, but are generating nearly 50% of those gun traces, and just OVER 50% of the actual gun crime. He's using those statistics to show that "gun violence" is an "epidemic" all over this state... but that is PATENTLY UNTRUE. There is an epidemic of violence (of all types) in some hardcore neighborhoods in tough cities. But, if all those people politically "on the fence" only hear that one unchallenged argument, what are they going to believe? The NRA needs to be doing broad-based advertising - short, snappy and to the point - that shows exactly where crime is happening, why it's happening, and who's committing it. The fact that we've allowed the anti-gun movement in states like ours to smear legal, law-abiding gun owners and the organizations that represent us as "monsters" with "blood on our hands" - and that we haven't hit back hard with a more compelling argument - is a strategic error of epic proportions.
