Not to be rude, but this isn't true. Only a few of our founding fathers were known to question the existence of God and all of these, in one way or another, adhered
in part to the teachings of Christian deism.
As John Adams stated, "The general principles on which the fathers achieved independence were the general principles of Christianity. I will avow that I then believed, and now believe, that those general principles of Christianity are as eternal and immutable as the existence and attributes of God."
Twenty-nine of the fifty six signers of the Declaration held what are today considered seminary or Bible school degrees in addition to their other accomplishments, and many others of the signers were bold and outspoken in their personal Christian faith. Significantly, not one of the Founding Fathers was atheist or secular in his orientation; even Thomas Paine (certainly the least religious of the Founders) openly acknowledged God and announced his belief in his personal accountability to God, and he also directly advocated teaching creationism in the public school classroom (See Paine's speech delivered in Paris on January 16, 1797).
And Ben Franklin was a baptized Puritan whose parents were devout Puritans who told Voltaire to his face that he believed in "God and liberty." Specifically, Ben Franklin referred to himself as a Christian deist in his 1771 autobiography.
See: Franklin, Benjamin (1771).

However; he stated that despite his Christian deist beliefs, he considered himself a Christian.
See: Olson, Roger (October 19, 2009).
The Mosaic of Christian Belief: Twenty Centuries of Unity and Diversity. InterVarsity Press. Other Deists and natural religionists who considered themselves Christians in some sense of the word included Thomas Jefferson and Benjamin Franklin.
He retained a strong faith in a God as the wellspring of morality and goodness in man, and as a Providential actor in history responsible for American independence.

He found it politically expedient to garner membership in a large number of wide ranging clubs, organizations, etc... and did so for political reasons not religious ones.
Not to be rude, but this really isnt true. Only a few of our founding fathers were known to believe in God, and most of them had a perverted belief in Him. Many of them were the kind who believed that salvation came from certain knowledge, and looked down on Christianity. Ben Franklin was a member of the Hellfire Club, a pagan group who mocked Christ and reveled in sinful acts. They were not really Christian, and looked down on those who were. They, like the leaders of today, fell into the demonic idea that because they are in power, they are divinely chosen, and believe in a pagan idea of God, and use Christianity with the belief that we foolish pawns they are given the divine right to rule over all are so foolish to follow, and pretend to believe in Christ in order to gain your trust.
I wouldnt believe any politician who called themselves Christian. We are warned, our enemy is the powers of the earth and of those fallen of the heavenly realms.
