Next in our series of primary races: Nebraska, a seat being vacated by the retirement of Mike Johanns.
Ben Sasse is considered the leading candidate to win the nomination. Sasse is the President of Midland University. He has a series of prominent endorsements, including the Senate Conservatives Fund, Club for Growth and prominent GOP leaders such as Tom Coburn and Paul Ryan.
He has been steadfastly conservative, opposing Obamacare among other things, though was criticized for his support of Medicare Part D.
The other major candidate is former State Treasurer Shane Osborn. Osborn actually has a significant history: he was the pilot at the Hainan Island incident. On April 1, 2001, Osborn was piloting an EP-3E airplane with a 23 member crew about 70 miles (110 km) away from the Chinese border when it collided with a Chinese fighter jet.
As Treasurer, Osborn focused on increased transparency for the state administration. He also put extensive effort into returning private property from the hands of government.
Freedomworks has endorsed Osborn, which sets the major conservative groups against each other in this race.
The other candidates, who are considered longshots, include Sid Dinsdale, President of Pinnacle Bank, Clifton Johnson, and attorney Bart McLeay.
