Jenna Bush Not Ready To Back McCain

The president and first lady may be solidly behind John McCain's candidacy, but one of their daughters isn't backing any candidate at the moment and even hinted at the possibility that she could even defy the family name by considering one of the Democrats.

"I don't know," she told CNN's Larry King when asked if she had a favorite between the Democratic candidates, reports the AP. "I mean, who isn't open to learning about the candidates? But, I mean, and I'm sure everybody is like that. But I really — I honestly have been too busy with books to really pay that much attention."

Jenna Bush was appearing with her mother on "Larry King Live" to promote their new book, "Read All About it."

This isn't the first time the child of a prominent politician has made headlines due to his or her allegiance—or lack there of—during the 2008 presidential campaign.

Last August, then GOP candidate Rudy Giuliani's daughter Caroline made news by posting on her Facebook profile that she was an Obama supporter.

And back in February, while Mitt Romney's son Josh was contemplating his own run for Congress, he said that he could not envision himself campaigning for John McCain.

"It's one thing to campaign for my dad, someone whose principles I line up with almost entirely," he told the Deseret News. "I can't say the same thing for Sen. McCain."
