However I believe more generally speaking the 2nd Amendment, or access to firearms by common folks, now has the potential to be a more prominent issue in the minds of a larger percentage of voters than it has been at any point in my lifetime.
This is thanks to the recent civil unrest and near total failure of authorities to protect citizens lives and property. We have all seen it with the record sales figures and anecdotal accounts of new ownership many of which are coming from quite unexpected quarters. To say nothing of Fudds who hopefully gained a new appreciation for that pistol in the drawer or shotgun in the closet.
The two people on the Democrat presidential ticket have both called for literal gun confiscation and I think continual pointing that out every day is certainly part of a winning argument in today's climate.
Further I do not believe for a minute that courts are not influenced by the mood of the country so more vocal support can't hurt.
