Remember that Lincoln is the left-wing capitol of Nebraska. The two largest employers in the city are the Government (it is the capitol of the State) and the University (it is home to the University of Nebraska. They are left-wing and will always be that way.
In Omaha, the City Clown-cilmen passed a "living minimum wage" law. The next election, all but two of them lost their seats (5 of 7 lost). The minimum wage was reversed. One of the two clown-cilmen that managed to get re-elected in spite of this tried to pass a smoking ban (several times). He lost his seat the next election.
Sounds like the people of Omaha are doing yeomans' work.
