Option 1) It loses its 3rd district, but regains it in a following census when it's put in Omaha.
Option 2) Massive population growth of the Kimball County area as a part of "greater frontrange".
Option 3) Large amounts of wind farm growth in the area bringing in workers who vote for the party more likely to support their jobs.
Wind farms don't require continuous labor like mines and oilfields do. They are unlikely to ever employ enough people to dominate a local economy. You would need a geothermal boom (requires continuous drilling/injecting) for that.
