LAS VEGAS-Clark County School District administrator Shirley Breeden will file today to challenge Republican state Sen. Joe Heck in Senate District 5.  Breeden had previously declared that she would seek the 21st Assembly District seat now held by Assemblyman Bob Beers.

According to a press release issued by the state Democratic Party, Breeden will seek the seat "because she believes more needs to be done to address the serious problems facing families and retirees in Nevada. She said the home foreclosure crisis, the public health crisis with the Hepatitis C outbreak and challenges facing our schools must be addressed now."

Although the district has been trending Democratic, Breeden will face a tough race to unseat Heck, who returned from a tour of Iraq with the Army Reserve Monday.  Heck filed for reelection Wednesday.

Breeden may face political troubles of her own as well. 

In 1997, she filed complaints against the school district with the Equal Employment Opportunity Commission and the Nevada Equal Rights Commission and sued in federal court over an incident in which she alleged that her supervisor retaliated against her for reporting sexual harassment.  Breeden's case made it to the Supreme Court, where in a 9-0 decision, the court overturned a Ninth Circuit ruling in favor of Breeden.

Expect to hear the term "frivolous lawsuits" thrown around freely in this campaign.
