(CNN) - Democrat Barack Obama said Friday that rival Hillary Clinton is trying to scare voters with a new television ad that raises the prospect of a foreign crisis over images of children asleep in their beds.
"We've seen these ads before," the Illinois senator said at a campaign event in Houston, Texas. "They're the kind that play on people's fears to scare up votes.
"Well, it won't work this time," he continued. "Because the question is not about picking up the phone. The question is: What kind of judgment will you make when you answer?"
The ad, launched Friday in Texas ahead of that state's crucial March 4 primary, shows children asleep in their beds in the middle of the night while a narrator references a potential national security crisis and asks, "It's 3 a.m. and your children are safely asleep. Who do you want answering the phone?"
Obama campaign manager David Plouffe denounced the ad in a conference call with reporters earlier Friday. And in his comments in Houston, Obama said, "We've had a red phone moment. It was the decision to invade Iraq. And Senator Clinton gave the wrong answer. George Bush gave the wrong answer. John McCain gave the wrong answer."
The Clinton campaign meanwhile vigorously defended the ad, and brushed aside notions it is reminiscent of the famous Lyndon Johnson "Daisy" ad, which portrayed a young girl counting down to a nuclear attack.
"This is a positive ad," Clinton adviser Mark Penn said. "Very soft images, not at all like that ad. Soft images. And it poses a question to people that they have to answer themselves: Who do they want to pick up the phone?"
"That ad basically envisions the apocalypse, and that is not what this ad does," Clinton communications director Howard Wolfson said. "This ad basically says, 'You know what? We are electing a president and it matters who is handling a phone call in a crisis at 3 a.m. as president.' That is a legitimate matter for a presidential campaign."
