A minor difference in that Palin actually said it herself. Wright wasn't speaking for Obama.
George Washington also quit his church because he refused to be pressured by the minister. He only attended to be with his wife.
"With respect to the inquiry you make, I can only state the following facts: that as pastor of the Episcopal Church, observing that, on sacramental Sundays George Washington, immediately after the desk and pulpit services, went out with the greater part of the congregation -- always leaving Mrs. Washington with the other communicants -- she invariably being one -- I considered it my duty, in a sermon on public worship, to state the unhappy tendency of example, particularly of those in elevated stations, who uniformly turned their backs on the Lord's Supper. I acknowledge the remark was intended for the President; and as such he received it. A few days after, in conversation, I believe, with a Senator of the United States, he told me he had dined the day before with the President, who, in the course of conversation at the table, said that, on the previous Sunday, he had received a very just rebuke from the pulpit for always leaving the church before the administration of the sacrament; that he honored the preacher for his integrity and candor; that he had never sufficiently considered the influence of his example, and that he would not again give cause for the repetition of the reproof; and that, as he had never been a communicant, were he to become one then, it would be imputed to an ostentatious display of religious zeal, arising altogether from his elevated station. Accordingly, he never afterwards came on the morning of sacrament Sunday, though at other times he was a constant attendant in the morning."

If I could conceive that the general government might ever be so administered as to render the liberty of conscience insecure, I beg you will be persuaded, that no one would be more zealous than myself to establish effectual barriers against the horrors of spiritual tyranny, and every species of religious persecution.

"I have diligently perused every line that Washington ever gave to the public, and I do not find one expression in which he pledges, himself as a believer in Christianity. I think anyone who will candidly do as I have done, will come to the conclusion that he was a Deist and nothing more."
-- The Reverend Bird Wilson, an Episcopal minister in Albany, New York, in an interview with Mr. Robert Dale Owen written on November 13, 1831, which was publlshed in New York two weeks later, quoted from Franklin Steiner, The Religious Beliefs of Our Presidents, pp. 27
"Washington never even got around to recording his belief that Christ was a great ethical teacher. His reticence on the subject was truly remarkable. Washington frequently alluded to Providence in his private correspondence. But the name of Christ, in any correspondence whatsoever, does not appear anywhere in his many letters to friends and associates throughout his life."
-- Paul F Boller, George Washington & Religion (1963) pp. 74-75, quoted from Ed and Michael Buckner, "Quotations that Support the Separation of State and Church." Had Washington been a pious Christian, he would have at least mentioned the name of Christ!
"That he [Washington] was not just striking a popular attitude as a politician is revealed by the absence of of the usual Christian terms: he did not mention Christ or even use the word 'God.' Following the phraseology of the philosophical Deism he professed, he referred to 'the invisible hand which conducts the affairs of men,' to 'the benign parent of the human race.'"
-- James Thomas Flexner, describing Washington's first Inaugural Address, in George Washington and the New Nation (1783-1793) (1970) p. 184, quoted from Ed and Michael Buckner, "Quotations that Support the Separation of State and Church"
"The founders of our nation were nearly all Infidels, and that of the presidents who had thus far been elected [Washington; Adams; Jefferson; Madison; Monroe; Adams; Jackson] not a one had professed a belief in Christianity....
"Among all our presidents from Washington downward, not one was a professor of religion, at least not of more than Unitarianism."

and John Rich's "Raisin' McCain" was awesome too.
