Hotline On Call

Now or Never PAC is jumping into Arizona's tight Senate race with a $1 million ad buy starting tomorrow. Their commercial is a brutal spot that invokes GOP Rep. Jeff Flake's hard-hitting attack ad going after Richard Carmona a few weeks ago.

The Now or Never PAC ad features a shadowy man banging on a door -- first with one hand, then with both hands.

Flake's ad earlier this month featured Carmona's former female boss relaying a story of Carmona coming to her house in the middle of the night. "There was an angry pounding on the door," she says. "In the middle of the night. I'm a single mom. I feared for my kids and for myself. It was Richard Carmona."

"Richard Carmona wants to be let in to the Senate," says the narrator of the new spot. "The handpicked choice of Obama, Carmona wants to knock down the door for his failed agenda. Supporting the Obamacare takeover, backing a $716 billion cut to Medicare and opposing the full extension of critical tax relief for small business. He's a threat to us. Richard Carmona. Don't let him in."

The Arizona Senate race has tightened this fall, and outside money has been pouring into the state.
