You appear to value your 2nd amendment rights. Did you vote for Trump?
Not everyone is a single issue voter and I doubt that "non gun owners" who convert suddenly decide that's their issue. My ex-wife modified her stance on guns over the years but wouldn't vote for anyone who would restrict abortion access, that was her "one issue".
Anyway, as long as you believe the NYT it's real: https://www.nytimes.com/interactive/...an-divide.html Trump also wins 48/50 states when it's divided into "rural vs urban" and "working class whites vs everyone else". Clinton, on the other hand, wins every state when it's "athiests vs everyone else".
Trump just needs to get everyone into a small country church and he'll win by a landslide.
