Gun rights are naturally associated with the GOP, but it’s a little more complicated than that; only the CLs and the Reactionaries (of course!) are passionate gun supporters. Guns have no appeal whatsoever for CDs, and they’re irrelevant to the PBP agenda.
Lots of PBPs are suburban women who have reason to fear uncontrolled gun ownership. Massacres with automatic weapons don’t exactly help sell them on the GOP brand. Is there an opening here for the Democrats?
Yes, if done properly. If your objective is to bring about the “revolution” by converting large numbers of reactionary white male workers, you would be wise to try to reconcile the Democrats’ agenda with gun ownership instead of attacking guns head on. But if your plan is merely to win the election by peeling off potential swing voters in the suburbs, you would be wise to hit this issue really, really hard in 2020.
