He was a
Democratic member of the
New York State Assembly in
1860 (
Kings Co., 3rd D.) and
1863 (Kings Co., 5th D.). In 1860, during the debate of black suffrage, he told the Assembly that "the proposition to put Negroes on a footing of political equality with white men is repugnant to the sense of the American people. They will never consent to share the proud title of 'American citizen' with an inferior and abject race." In March 1861, Callicot assisted
Mitchell Sanford to defend Assemblyman
Jay Gibbons at the latter's trial before the Assembly on charges of bribery. After Sanford's unexpected death on March 29, Callicot pleaded on behalf of Gibbons until the latter was expelled by the Assembly on April 3. In 1863, the
New York State Assembly was tied, having 64
Republicans and Democrats each. The election of a
Speaker proved to be difficult. During the stalemate, Callicot offered the Republican leader
Chauncey M. Depew a deal: If the Republicans elect him Speaker, then Callicot would help the Republicans elect a
U.S. Senator from New York. Depew accepted, and on January 26, Callicot was elected Speaker on the 92nd ballot. Shortly afterward, the Democrats accused Callicot of improper and corrupt proceedings to achieve his election as Speaker and a Select Committee was appointed to investigate. On April 20, the Assembly adopted the majority report of the Select Committee, declaring Callicott "entirely innocent." At the next state election he was defeated for re-election to the Assembly. ==Federal office==
