Now with Sheehy likely out of the mix for Nebraska's next Governor, the race is becoming highly unpredictable and it hasn't even started.
The resignation of Sheehy, a Republican who had enjoyed the endorsement and fundraising efforts of Governor Dave Heineman is the latest twist.
Months ago another candidate who many thought to give it a run, Mike Flood, withdrew after his wife was diagnosed with breast cancer.
Some speculate Republicans who could run include Senator Beau McCoy, Attorney General Jon Bruning and Nebraska Regent Tim Clare.
Democrat candidates that have shown interest include Regent Chuck Hassebrook, State Senator Steve Lanthrop and State Senator Annette Dubas.
