64, titled "The Power of the Senate", is an essay first published in The New York Packet on March 5, 1788, by John Jay as part of the ongoing Federalist Papers.

Throughout the Federalist Papers, James Madison, Alexander Hamilton, and Jay emphasize the particular role in the field of foreign affairs (Golove).

This essay in the Federalist Papers is very influential, discussing the idea of treaties, the mystery behind the author, and the invalidity of the Anti-Federalists' argument.

64, Jay defends the provision in the Constitution that grants the President the power to make treaties with the consent of two-thirds of the Senate.

While the "advise and consent" clause was typically understood to give the Senate power to oversee treaty enactment, Jay interpreted the clause as giving the President the power to decide when he wanted to seek "advise and consent" from the body.

[3] With this being noted, Jay expresses his stance that the Senate represents the state issues and is less knowledgeable in foreign affairs than the President.

This concept also supports Jay's belief that the Constitution creates a strong national government that favors the Senate.

The writer agrees that the Senate taking part will be beneficial but thinks that it will eventually become "the source of the greatest evils".

[4] Finally, Anti-Federalist 64 speaks about the beliefs that the constitution of the Senate sends fear and little hope to the democratic rights.

The second theory is that Jay asked Hamilton and Madison to hide his involvement in the Federalist Papers because his writing was not strong enough; however, this information came from an unidentified source.
