In an Oct. 24, 1787, letter to Thomas Jefferson, James Madison expressed that, “Col. [George] Mason left Philadelphia in an exceeding ill humor indeed. A number of little circumstances arising in part from the impatience which prevailed towards the close of the business, conspired to whet his acrimony. He returned to Virginia with a fixed disposition to prevent the adoption of the plan if possible. He considers the want of a bill of rights as a fatal objection.”
At the Constitutional Convention, in mid-September 1787, committed Anti-Federalists George Mason and Eldridge Gerry failed to persuade any of their fellow delegates to preface the Constitution with a bill of rights.
