Sen. Clinton's campaign aired a commercial Friday that has caught the attention of her opponent, Sen. Obama.
"Your vote will help decide who answers that call," Sen. Clinton said in the commercial. "I'm Hillary Clinton, and I approved this ad."
"In the world that we face with both the challenges and opportunity, we need a president who picks up that phone ready to decide," Clinton added.
Sen. Obama responded by calling the ad a political method to acquire votes.
"We've seen theses ads before. They are usually the kind that play on people's fears and try to scare up votes."
The most controversial commercial was the 1964 advertisement that asked people to vote for President Lyndon B. Johnson, that showed images of an atomic bomb explosion.
The commercial only aired once during the 1964 presidential campaign. Though many credit it with contributing to President Johnson's landslide defeat of his opponent.
Paul Steckler is a communications professor at the University of Texas and said the advertisement works.
"I think this is a perfectly legitimate ad," he said.

He's also an expert when it comes to campaign advertising.
"The Clinton campaign has been trying to take advantage of the fact that she's been around national politics for a long time. That she'll be ready on day one. This is sort of a more creative use of that," Steckler said.
Sen. Obama thinks otherwise.
"I don't think these ads will work this time because the question is not about picking up the phone. The question is what kind of judgment will you exercise when you pick up that phone," Obama said.
Just hours after Sen. Obama said those words, he released a new advertisement aimed to counter the Clinton ad.
Both campaigns are hoping Texans take heed of their campaign advertisements when it comes time to vote.
