Chris Christie has launched his first TV ad of the New Jersey gubernatorial race this morning, which plays up his experience as U.S. Attorney and pledges to fix a broken state.

It's partly a biographical ad, but rather than warm and fuzzy, there's a "Law & Order" feel to the narration and music -- perhaps fitting the tough image the campaign tries to project.

"As US Attorney Chris Christie went after corrupt politicians," the narrator says. "He tracked down child pornographers across the globe, and prosecuted corrupt business executives. Today, Chris Christie runs for Governor."

Though he still has a Republican primary to get through, Christie targets Gov. Jon Corzine's tax policy in the ad. Taxes will likely be one of the top issue in the campaign. It does not mention that Christie is a Republican, saying instead that he'll fix New Jersey "just as he did as US Attorney, with leadership, independence, determination."

It's still early in the campaign, but the spot comes later than the first ad of the 2005 campaign did. Then, businessman Doug Forrester actually went on the air in November of 2004. But that year, the Republican primary was a bit more crowded and competitive.

The campaign says the ad will air in both the New York and Philadelphia markets -- expensive turf, which makes any campaign in the Garden State difficult. The campaign says that with strong fundraising, it is right on track with when it planned to go on TV.

Here's the ad:
