Some history and backstory on the endorser, for perusal:

According to interviews with 10 people who worked on the race, Bilbray's campaign lacked a clear strategy. She got caught between party operatives in Washington telling her to sit in a room to make fundraising calls and her supporters in Nevada saying she should get outside to shake hands with voters.
Churning through three campaign managers in eight months, her campaign never gained traction with voters or even her own party leaders.
Bilbray's defeat underscores just how important money and Washington party support is to congressional campaigns. At an estimated $4 billion, this was the most expensive midterm in history, and campaigns are only getting more expensive since a 2010 Supreme Court decision that allows corporations to spend unlimited amounts to influence elections.
Bilbray and her supporters say she did all she could against a Republican incumbent in a year when Republicans swept the state. They say she ran a well-coordinated, organized and focused campaign."I think she's a perfect candidate in a horrible year," said Adriana Martinez, Bilbray's third and final campaign manager and her close friend.
