I can hardly accept that a person (bobo) is willing to bet the farm merely on the belief that "...rednecks and farmers" will be the difference in this political race. I DO beleive that rednecks and farmers hold the balance of votes in this 'farming/agricultural state.' But, that is not how bobo is using his meaning of rednecks and farmers.
Unfortunately, we all know what bobo really means; and there is that percentage. I've only visited there, but based on my visits, I believe strongly on the way you describe it Chris.
