Sen. Maria Cantwell's first TV commercial of the campaign season began airing today. It's called "First" and runs 30 seconds.

It focuses on Cantwell's energy work, with shots of newspaper headlines relating to her dogging of Enron and calling for an investigation of gas price gouging.

You can watch it here.

It's pretty much a sticking-up-for-the-little-guy ad as well as a way to show voters that Cantwell has been busy in D.C. (You know, just in case like Dal LaMagna you haven't been getting your telephone calls returned.)

It's running on cable in all the state's media markets.
