Audio: “I am Barbara Bush, and I am a New Yorker for marriage equality. New York is about fairness and equality. And everyone should have the right to marry the person that they love. Join us.”

Her support is not overly surprising as Barbara has shown that her political beliefs aren’t exactly in line with her dad’s in the past. She supported Obama’s Health Care plan. More over, she attended a fundraiser last September for the pro-freedom to marry American Foundation for Equal Rights (AFER) in New York City.

Of course, Barbara Bush isn’t the first political child to come out and support something that was in rather stark contrast to that of their parents. In fact, there must be something about being the child of a President that makes children more likely to go the other way.

Take for example Patti Davis, President Reagan’s daughter who uses her mom Nancy’s maiden name. She was “the most rebellious of the three kids — she was vocally pro-choice, anti-nuke and even posed nude for Playboy.”

And then there’s Julie Nixon Eisenhower, youngest of Nixon’s daughters, who — gasp — supported Obama in 2008.

So, it’s not really like Barbara Bush is the first to do something or support something that her political parent(s) wouldn’t have or might not approve of. In fact, I found it more shocking (in a good way) Laura Bush, G-Dub’s wife, supported equal rights for same sex partners. And then there was the mother-daughter pairing of Cindy and Meghan McCain for the NOH8 campaign.

Barbara’s PSA has made some waves in the blogosphere, of course. All sorts of various topics are being discussed regarding her support.
