It's become a war of words on the air waves in the race for Nassau County's top prosecutor.

Democrat Todd Kaminsky is facing Republican Anne Donnelly to become the next district attorney.

An ad for the Kaminsky campaign states, She {Anne Donnelly} failed when it mattered most, botched a murder-for-hire case after lying to a judge. Then an ad for Donnelly's campaign says Todd Kaminsky is too dangerous to be Nassau's DA.

In the top law enforcement job in Nassau, words mean everything, and experience is just as valuable.

"I know where our strengths are and where we can use some improvement," says Donnelly.

Donnelly is a 32-year veteran of the Nassau District Attorney's Office, and says she can hit the ground running if elected.

Kaminsky is a state senator from Long Beach who used to be a federal prosecutor. He says he's never lost a case.

"I prosecuted everyone from gang leaders and drug kingpins to gun traffickers, all the way to corrupt politicians from both parties," says Kaminsky.

Both candidates say they've worked with former DA Madeline Singas, who left office to become a state Appeals Court judge.

Polls show reducing crime is a top issue among voters and both pledge they will be tough but fair. One key issue is New York state's new bail reform laws.
