Outgoing Alaska Governor Sarah Palin passed along this wisdom on her Twitter feed earlier today. Because the quote, as she recounts it, is so garbled, it is indeed difficult to know who actually said it. But, it sounds remarkably similar to the John F. Kennedy Library Foundation's description of its Profile in Courage award.
The award is named for President Kennedy's 1957 Pulitzer prize-winning book, Profiles in Courage, which recounts the stories of eight U.S. Senators who risked their careers by taking principled stands for unpopular positions.The Profile in Courage Award seeks to make Americans aware of the conscientious and courageous acts of their public servants, and to encourage elected officials to choose principles over partisanship – to do what is right, rather than what is expedient.
Here's an earlier version: 
Both descriptions echo the famous 1960 speech in which Kennedy addressed the subject of religion. Said Kennedy then:
I am the Democratic Party's candidate for President who happens also to be a Catholic.There's something going on here. Irony? Projection? Ignorance? I'll leave that up to you.I do not speak for my church on public matters; and the church does not speak for me. Whatever issue may come before me as President, if I should be elected, on birth control, divorce, censorship, gambling or any other subject, I will make my decision in accordance with these views — in accordance with what my conscience tells me to be in the national interest, and without regard to outside religious pressure or dictates. And no power or threat of punishment could cause me to decide otherwise.
But if the time should ever come — and I do not concede any conflict to be remotely possible — when my office would require me to either violate my conscience or violate the national interest, then I would resign the office; and I hope any conscientious public servant would do likewise.

She takes her cues from Julia - The Pink Ranger.
That would make her a Ted Sorenson fan.
I think that this was actually lifted from that Miss Teen South Carolina "U.S. Americans such as Africa" gal's livejournal.
Maybe I'm a media rube--but--WOW. I am mystified and impressed by your ability to synthisize a Sarah Palin musing with a JFK speech. But then I am deeply in love the idea of you.
More of a profile in boorage.
Ha!
I am starting to get the creepy feeling that her inarticulateness - like George Bush's - actually helps her. The crap that she spouts is so scattershot and vague that her literacy-challenged fans can read whatever they like into it.
Seconded, and terrified.
Like a horoscope, but in this case, it's a horrorscope.
Or like the Palin-Ching
"I can not and will not alter the hemline of my conscience to fit this year's fashions. However, I will put on waders to club fish."
I think she is considering a conversion to Islam, because it seems to have worked so well for Obama.
