 Cantacuzino presented himself as a candidate in the princely election of December, but only managed 41 of 188 votes; the winner was Bibescu.Initially, Bibescu promoted him, assigning him office as an "Efor" of the Wallachian schools, jointly with Filipescu-Vulpea and Mihalache Ghica.Like his brother Grigore (who sat in the Assembly's committee for educational review), Constantin was a reactionary who objected to educational reform.
