Fred Davis is the Hollywood ad guru notorious for John McCain’s “celebrity” attack ad on Barack Obama, Carly Fiorina’s “demon sheep” spot against Tom Campbell, and now, this ominous spot against Barbara Boxer.

Known for his use of offbeat metaphors, Davis this time characterizes Boxer as “elitist” by inflating her up as a blimp who flies over California, and so obsessed with climate change legislation that she wants to pass it at all costs. Then we get relief in the form of Davis’ client, Fiorina, who is engaged in a competitive Republican primary race against Chuck DeVore and Tom Campbell.

The Web video’s tone is a mixture of “Independence Day” with a narrator who sounds like Paul Frees, the voice of Disneyland’s Haunted Mansion attraction. (It’s not Frees, who passed away in 1986).

As with all of Davis’ work, you have to see it to believe it. The title: “Hot Air: The Movie.”

Boxer’s campaign manager, Rose Kapolcynski, issued this response: “Not even another bizarre video can distract voters from Fiorina’s record as a failed CEO who laid off 28,000 workers and shipped California jobs overseas. While Fiorina spends time producing works of fiction, Barbara Boxer is focused on creating good jobs in California and getting our economy back on track.”
