Basically, it is my understanding that to BRTD's dismay, Indiana is just a northern leg of the Bible Belt as most people from Indiana are really from, what I head from a professor from Indiana who was the mayor of the town, that most Hoosiers are from Kentucky and Tennessee.
Yeah, it's called the butternut region, a long band of counties north of the Ohio River that were settled by Southerners and retained many aspects of Southern culture. This extends throughout Illinois and Ohio in addition to Indiana, and, as BRTD said, means that the rural areas of the greater part of these three states are conservative.
