At Boston, a newspaper hailed his 1817 visit as the beginning of an "Era of Good Feelings". Frequent stops on his tours included ceremonies of welcome and expressions of good-will. The Federalist Party continued to fade during his administration; it maintained its vitality and organizational integrity in Delaware and a few localities, but lacked influence in national politics. Lacking serious opposition, the Democratic-Republican Party's Congressional caucus stopped meeting, and for practical purposes the party stopped operating. Monroe appointed a geographically-balanced cabinet, through which he led the executive branch. At Monroe's request, Crawford continued to serve as Treasury Secretary. Monroe also chose to retain Benjamin Crowninshield of Massachusetts as Secretary of the Navy and Richard Rush of Pennsylvania as Attorney General. Recognizing Northern discontent at the continuation of the Virginia dynasty, Monroe chose John Quincy Adams of Massachusetts as Secretary of State, making Adams the early favorite to eventually succeed Monroe. An experienced diplomat, Adams had abandoned the Federalist Party in 1807 in support of Thomas Jefferson's foreign policy, and Monroe hoped that the appointment would encourage the defection of more Federalists. After General Andrew Jackson declined appointment as Secretary of War, Monroe turned to South Carolina Congressman John C. Calhoun, leaving the Cabinet without a prominent Westerner. In late 1817 Rush became the ambassador to Britain, and William Wirt succeeded him as Attorney General. With the exception of Crowninshield, the rest of Monroe's initial cabinet appointees remained in place for the remainder of his presidency. In February 1819, a bill to enable the people of the Missouri Territory to draft a constitution and form a government preliminary to admission into the Union came before the House of Representatives. During these proceedings, Congressman James Tallmadge, Jr. of New York "tossed a bombshell into the Era of Good Feelings" by offering the Tallmadge Amendment, which prohibited the further introduction of slaves into Missouri and required that all future children of slave parents therein should be free at the age of twenty-five years. After three days of rancorous and sometimes bitter debate, the bill, with Tallmadge's amendments, passed. The measure then went to the Senate, where both amendments were rejected. A House–Senate conference committee was unable to resolve the disagreements on the bill, and so the entire measure failed. The ensuing debates pitted the northern "restrictionists" (antislavery legislators who wished to bar slavery from the Louisiana territories) against southern "anti-restrictionists" (proslavery legislators who rejected any interference by Congress inhibiting slavery expansion).
