In Nebraska, Bruning is facing state Treasurer Don Stenberg (R) and state Sen. Pat Flynn (R). Both have run for Senate before, and haven't won a general election. Stenberg launched his campaign in March and immediately attacked Bruning for some views the attorney general expressed in op-eds he wrote for as student paper during law school espousing liberal viewpoints. Tea Party Express spokesman Sal Russo hinted that electability was a factor in the group's endorsement. Both Stenberg and Flynn have made Senate runs in the past, never winning a general election. "Stenberg has run three times for this U.S. Senate. He lost two primaries. I don't think his campaigns have been the strongest," said Russo. But The Tea Party Express also said they're enthusiastically backing Bruning because he best meets the group's criteria for selecting candidates. Russo said the group endorses candidates who are in step with the group's commitment to ending "reckless spending" and addressing the nation's debt - and also look for candidates who demonstrate moral courage. "He meets our criteria better than any other candidate in Nebraska," said Russo. For his part, Bruning said he does not agree the Tea Party movement in Nebraska isn't satisfied with the endorsement. "I think to say the Tea Party movement in Nebraska is dissatisfied with this endorsement is inaccurate," said Bruning, who also noted that he has been to "many, many Tea Party rallies in Nebraska" and has "a lot of good friends" among the Tea Party movement in the state of Nebraska.
