So far a lot of people are buying some extra ammo or components, some are definitely buying firearms(especially EBR types), but there's still ammo on the shelves, and powder, and no long lines- at least around here- to fill out a yellow sheet.
I'm guessing that a lot- probably most- have decided that if the three branches are split between parties it'll keep Clinton- if she wins- from just shoving through some of the crap she's pushed. Especially since she's not going to get any honeymoon 'be nice to the winner' period. So "I'm going to pick up some extra ammo/primers/powder/bullets just in case, but I'm not doing that panic-buying again."
The 2nd is still under threat, especially if Clinton gets to nominate some judges, but the widespread panic doesn't seem to have started. At least not yet.
