Yep I watch and actually admire some of these folks... they have conviction.
They understand the insanity of the world they live in, and are doing their best to look to the future. Sad, though, that they all foresee disaster. ( Of course, that is the premise of the show

)
One lot were particularly engaging, and stupid.
They determined that the likeliest doomsday scenario was nuclear attack. They picked a really nice wilderness place for their family. They set up an amazing solar power system as their primary source of energy.
The failing in their prep that I noticed, and the producers who rate the preppers also failed to understand, was that in the event of a nuclear attack, or attacks,

we get what is called a 'nuclear winter'.
The sky is heavy with poisonous clouds, and the SUN, is not available to power their planned powerplants.

Poor buggers.

The prevalence of weapons is also notable for their apparent usefulness. I wonder what or who, they'll be targeting.
All of them are thinking.. 'other people'. They are creating their own disaster if they vote for Trump.
But I think (hope) that sanity will prevail, and Trump will be trumped by Hillary.
Mark my words... this is THE watermark Election.
The US will continue as a world power if Clinton becomes President.
You want Trump? .. you are party to the destruction of the United States of America.
Spoken as a citizen from a country other than the USA.
