Movimiento V República
In July 2000, following the 2000 Venezuelan regional elections, he became the first Mayor of Caracas (Alcaldía Mayor de Caracas, a position that replaced the Venezuelan Federal District) for the Fifth Republic Movement after winning the elections by a landslide. His nomination for Mayor by the Fifth Republic Movement created division within the party, as Aristóbulo Istúriz, chair of the party Patria Para Todos, also wanted the position. Patria Para Todos then abandoned the coalition with the Fifth Republic Movement, only to join it again 18 months later.
