In case of an election night Doomsday, preppers are running up sales of emergency survival food.

While sales for "long term food" typically see an increase around natural disasters and elections, "this is more intense than what we saw in 2012," said Keith Bansemer, VP of marketing for My Patriot Supply, a manufacturer and seller of survival food. During the previous election his company saw sales double. This time it's triple.

"We have everyone we can on the phones," he said. "We are overwhelmed."

Purchases at other long term food supply companies are up as well. Emergency preparedness online store TheEpicenter reports a 6 percent uptick in year over year sales.

Another company, Legacy Foods, predicts they'll see a 1-2 week spike in sales after the election -- if Hillary Clinton wins, said owner Phil Cox.

The meals, sold by the plastic bucket or tote bin, are typically dehydrated or freeze-dried food in sealed military-grade Mylar packs. Menu items include pasta primavera, Hawaiian Style Sweet n' Sour, cheesy broccoli and rice soup, orange energy drink mix and chocolate pudding. They're sold in bundles based on how long they'll feed you.
