Why is Kansas more Democratic than Nebraska?

I also think it has something to do with it's larger cities. Topeka, Kansas City, and Lawrence are all strongly Democratic, while Nebraska's largest cities Lincoln and Omaha are swing to maybe just lean Democratic.

In 2012, the only Democratic county in Nebraska was a Native American reservation; Lancaster County (Lincoln) very, very narrowly went to Romney, same with Douglas County (Omaha).

In Kansas, the only two Democratic counties in the state have relatively high populations for Kansas and both Wyandotte (Kansas City) and Douglas (Lawrence) went strongly +60% to Obama.

So even in Lincoln, which contains Nebraska's main university, went Republican, while Kansas's main university located in Douglas County, went fairly strongly for Obama.

I guess now a better question would be why is University of Kansas more liberal than University of Nebraska?
