Kentucky bartending

Rico says his friend Tex sends this:

A man walked into a bar in Lexington, Kentucky and ordered a drink. While he was sitting at the bar watching television, one of Obama's political ads came on. After it ended, he announced to everyone: "Obama is a horse's ass".
The bartender reached under the bar and brought out an oak club about eighteen inches long and hit the man square across the mouth, knocking him off his stool and onto the floor.
After a minute or two, the man got up, straightened himself up, and said to the bartender: "I'm sorry. I didn't know this was Obama country"
"It's not!" replied the bartender. "This is horse country."
