I am somewhat familiar with small town America.  I don't believe that those who see a facebook ad showing the devil armwrestling jesus and think "by gar ah'd better vote fer this trump feller" are in a majority.

they might listen to their preacher regarding a vote, but that's a different issue.

if I am wrong about their sway on the elections then I will start to upvote those guys who keep saying the world is doomed...
