Most of the voters who vote Republican are usually rural. They're the people out in the middle of bumfuck no where, with their farms, their farm animals and what little family they have. And all that they can afford are things like dial-up internet. So they're completely out of touch with more 'civilized' people who're in towns and cities. And even so, there are people who are completely nuanced and naive to what is before them even with better access to information. They can't and won't challenge their intellect, they won't question information as to what's infront of them. Nothing. Just deliberately clueless and oblivious.
