SEATTLE -- Opening night is in sight for an up-and-coming Seattle performer and playwright.

She's not someone you'd expect. She is former Washington State Insurance Commissioner Deborah Senn, about to debut in a one-woman show.

"First I went after Blue Cross Blue Shield, round one," says Deborah Senn, on stage.

She's used to the political stage. But here is veteran campaigner Deborah Senn on a theatrical stage, rehearsing a play she wrote called "Until the Last Dog Dies."

Senn was a theatre major in college. This is actually the second play she's written.

"People in politics are creative. They always say scratch a lawyer and find a screenwriter or playwright," she said.

The play focuses on Senn's unsuccessful 2004 run for attorney general in which she was targeted by more than $1 million in negative ads.

Ad: "Who is Deborah Senn looking out for?"

The ads were the work of the U.S. Chamber of Commerce, which is still resisting court orders to reveal who paid for them.

"In all seriousness the, U.S. Chamber of Commerce who did this to me are doing it to Supreme Court justices all over the country."

Senn lost the election, and is now venting some frustrations creatively.

"Round two, I went after their fat salaries"

"So I went to the Rep, I saw this one-person show. Wow, I'm going to write a solo show! And the first draft sounded like a legal brief, let me tell you, the first draft -- it was boring."

Many rewrites later, she says the show now has lots of laughs.

"Round three, I sued them for making people get prior approval for going to the emergency room. You gotta call before the accident?"

If you want to see whether Deborah Senn scores a knockout from the stage, the show will be running Thursday through Sunday at the Capitol Hill Arts Center.
