Here is the insight of one of the best political minds ever to exist on the influence of Christianity early in the history of the US.
So, was the US founded on Christian principles and Christian ideas? Absolutely according to Alexis de Tocqueville. He came to this conclusion after spending 2 years traveling around the US both geographically and politically. He mingled with the people on a regular basis and spent many an evening in the local taverns to eat and listen to the ongoing political discussions for there it was the custom of the people to gather around and discuss the current political events of the time. He was also give access to many of the historical records at most levels of government from townships, to counties, to states. I do not know if he was offered access to federal levels, but that is not too important for at the time the vast majority of political power was held at the township and county levels.

In the United States the influence of religion is not confined to the manners, but it extends to the intelligence of the people. Amongst the Anglo-Americans, there are some who profess the doctrines of Christianity from a sincere belief in them, and others who do the same because they are afraid to be suspected of unbelief. Christianity, therefore, reigns without any obstacle, by universal consent; the consequence is, as I have before observed, that every principle of the moral world is fixed and determinate, although the political world is abandoned to the debates and the experiments of men. Thus the human mind is never left to wander across a boundless field; and, whatever may be its pretensions, it is checked from time to time by barriers which it cannot surmount. Before it can perpetrate innovation, certain primal and immutable principles are laid down, and the boldest conceptions of human device are subjected to certain forms which retard and stop their completion.
The imagination of the Americans, even in its greatest flights, is circumspect and undecided; its impulses are checked, and its works unfinished. These habits of restraint recur in political society, and are singularly favorable both to the tranquillity of the people and to the durability of the institutions it has established. Nature and circumstances concurred to make the inhabitants of the United States bold men, as is sufficiently attested by the enterprising spirit with which they seek for fortune. If the mind of the Americans were free from all trammels, they would very shortly become the most daring innovators and the most implacable disputants in the world. But the revolutionists of America are obliged to profess an ostensible respect for Christian morality and equity, which does not easily permit them to violate the laws that oppose their designs; nor would they find it easy to surmount the scruples of their partisans, even if they were able to get over their own. Hitherto no one in the United States has dared to advance the maxim, that everything is permissible with a view to the interests of society; an impious adage which seems to have been invented in an age of freedom to shelter all the tyrants of future ages. Thus whilst the law permits the Americans to do what they please, religion prevents them from conceiving, and forbids them to commit, what is rash or unjust.
Religion in America takes no direct part in the government of society, but it must nevertheless be regarded as the foremost of the political institutions of that country; for if it does not impart a taste for freedom, it facilitates the use of free institutions. Indeed, it is in this same point of view that the inhabitants of the United States themselves look upon religious belief. I do not know whether all the Americans have a sincere faith in their religion, for who can search the human heart? but I am certain that they hold it to be indispensable to the maintenance of republican institutions. This opinion is not peculiar to a class of citizens or to a party, but it belongs to the whole nation, and to every rank of society.
In the United States, if a political character attacks a sect, this may not prevent even the partisans of that very sect from supporting him; but if he attacks all the sects together, everyone abandons him, and he remains alone.
