Washington (CNN) -- The weirdest campaign ad of this season -- maybe any season -- debuted on the Internet this past week. The ad has been nicknamed, "Demon Sheep," and can be viewed here. The ad is an opening salvo in what will could prove the most expensive Senate race in U.S. history. The incumbent, Barbara Boxer, has always been the less popular of California's two Democratic senators. Boxer now looks vulnerable. Two Republicans declared early for the nomination against Boxer: state Sen. Chuck DeVore and former Hewlett Packard CEO Carly Fiorina. Fiorina took an early lead. But her performance on the campaign trail disheartened many of her supporters. Worse, Fiorina never developed a good answer to the questions about her business career. Portfolio magazine had dubbed Fiorina one of the 20 worst CEOs of all time after a disastrous merger with Compaq.

David Frum says it may be the strangest campaign ad ever

He says she's unfairly targeting Tom Campbell as a fiscal conservative in name only

Frum says Campbell acted responsibly to try to head off the fiscal crisis California is now in
He helped write the 2005 @placeholder budget, which contained a big jump in state spending.
@placeholder's budget position was already desperate when Campbell took the job.
• @placeholder's "three-strikes" law -- life in prison after a third felony conviction -- had filled the state's correctional institutions with doddering old crooks confined forever at taxpayer expense.
