Well, consider the arguement in it's most basic form:
"Theres a NEW GUN that ANYONE COULD HAVE and it's INVISIBLE-ish! Vote for us to PROTECT YOU! DONT VOTE THE OTHER BECAUSE YOU SHOULD BE AFRAID!"
Utterly ludecrous from the beginning to the end, but let's look at the other side:
"Overreaction party will BAN MAKING THINGS and YOU WILL STARVE! Vote for us to help you NOT BE POOR! DONT VOTE THE OTHER BECAUSE YOU SHOULD BE AFRAID!"

In short politics... One side isn't going to ban a damn thing (though extremests on that side want to ban every damn thing everywhere forever), and the other isn't going to flood the streets with crazy people guns for crazy people (though extremests on that side want crazy people guns stuffed in every pocket of their clothings).

To sum up, not everyone in America is crazy... Not even everyone in American Politics is crazy... But dammit, everyone crazy in America is crazy about politics.
