(p. 330) Jefferson traced the formation of the two main parties–to be known as Republicans and Federalists–to Hamilton’s victory over assumption. For Jefferson, this event split Congress into pure, virtuous republicans and a “mercenary phalanx,” “monarchists in principle,” who “adhered to Hamilton of course as their leader in that principle.”
Why did Jefferson retrospectively try to downplay his part in passing Hamilton’s assumption scheme? While he understood the plan at the time better than he admitted, he probably did not see as clearly as Hamilton that the scheme created an unshakable foundation for federal power in America. The federal government had captured forever the bulk of American taxing power. In comparison, the location of the national capital seemed a secondary matter. It wasn’t that Jefferson had been duped by Hamilton; Hamilton had explained his views at dizzying length. It was simply that he had been outsmarted by Hamilton, who had embedded an enduring political system in the details of the funding scheme. In an unsigned newspaper article that September, entitled “Address to the Public Creditors,” Hamilton gave away the secret of his statecraft that so infuriated Jefferson: “Whoever considers the nature of our government with discernment will see that though obstacles and delays will frequently stand in the way of the adoption of good measures, yet when once adopted, they are likely to be stable and permanent. It will be far more difficult to undo than to do.”
