I know plenty of people who will buy more guns and ammo if Zippy wins. Very sensible.
You don’t need to stock up on bread and milk when there is no emergency. You can get them whenever needed. But if you think the supply will be cut off, you need to stock up ASAP.
I would also advise people to learn to reload for an emergency. Loading your own ammunition will prove to be one of the most valuable skills in a SHTF scenario. I took up reloading this year and just passed my 4000th round.
Also bought a furnace to cast my own bullets should the need ever arise.
