What makes Oklahoma different?

Tonight I was checking out the elections on a state by state basis looking for trends and things of that nature. Naturally, I started to check out the home state I grew up in.

Two glaring things I noticed:

1) Oklahoma has their election process down... It was one of the first states to reach 100% results in even though it is in the middle of the country. Either that or people dang sure had their mind made up.

2) Look at the picture below... Wow, that's the only state I found that way!
