Appearing with her mother on Larry King’s show this week, first daughter Jenna Bush left open the possibility that she might not vote for John McCain in November:

KING: Do you have a favorite between the two, the two Democrats?

LAURA BUSH: My favorite is the Republican.

(LAUGHTER)

KING: Yours, too, I would imagine.

JENNA BUSH: I don’t know.

KING: A-ha. J. BUSH: But, I mean, you know –

KING: Are you open to –

J. BUSH: Yes, of course. 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.

If Jenna were to support a Democrat this year, she would be the second daughter of a Republican president to switch parties so far. Earlier this week, the Associated Press reported that Julie Nixon Eisenhower, daughter of GOP Pres. Richard Nixon, had donated $2,300, the legal limit, to Barack Obama.

Susan Eisenhower, the granddaughter of GOP Pres. Dwight Eisenhower, is also an Obama supporter.

Ronald Reagan’s daughter, Patti Davis, came over from the dark side long ago but if she has announced whom she is supporting this year we missed it. However, she did write an article that was published in Newsweek last December, requesting that the midgets who were seeking the Republican nomination stop comparing themselves to her father.
