Using a theoretical framework that values institutional political experience and social capital as sources of maintenance of the political elite that composes the political institutions, studies focused on Brazil's bicameral Congress were synthesized in data and conclusions that corroborated for the understanding of the Brazilian political institutions dominated by a cohesive elite, with low circularity and high socioeconomic resources that projects them to the highest positions on Legislative. Questioning the possible dissonance between parties leaders and parties members in the Federal Senate, there was a 'leader profile' that overcame the intrinsic differences of parties on the political spectrum, where Senators that have graduated in engineering overcame the numerical dominance of law graduates in Brazil's Federal Senate, which as one half of the country's Congress is marked by long-serving career politicians, with parties leaders being even more experienced Senators, mainly with political careers built by Legislative mandates. / Atrav?s de um estudo acerca do social background, das carreiras e trajet?rias pol?ticas de Senadores que foram al?ados aos postos de l?deres de partidos e blocos suprapartid?rios do Senado Federal entre 1999 e 2006, este trabalho evidencia que, no que tange ?s 51? e 52? Legislaturas, o col?gio de l?deres concentrou e exacerbou as principais caracter?sticas dos componentes da Casa. Valendo-se de um arcabou?o te?rico que valoriza a experi?ncia pol?tica e o capital social como fontes de manuten??o da elite que comp?e os meios institucionais, retomou-se estudos de caso focados no Congresso Nacional, sintetizados em dados e afirma??es que corroboraram para a compreens?o da pol?tica institucional brasileira dominada por uma elite coesa, de baixa circularidade e de elevados recursos socioecon?micos que os projetam para os cargos mais elevados do Legislativo. Tendo questionado a poss?vel disson?ncia entre os Senadores l?deres e liderados, encontrou-se um perfil de l?der que supera as diferen?as intr?nsecas das legendas na escala ideol?gica, onde os Senadores engenheiros se sobrepuseram a domin?ncia dos bachar?is em Direito na Casa da Federa??o, que como institui??o legislativa marcada pelos pol?ticos de carreiras longevas, tinha no col?gio de l?deres, Senadores ainda mais experientes, principalmente com carreiras pol?ticas constru?das por mandatos no Legislativo.
