The PSD-supported candidate Aníbal Cavaco Silva won the Portuguese presidential elections in 2006 and again in 2011. After the 2005 elections, Luís Marques Mendes was elected leader of the party. Internal infighting weakened Marques Mendes and, in September 2007, Marques Mendes was defeated by Luís Filipe Menezes by a 54% to 42% margin. Menezes was also incapable with dealing with his internal opposition and, after just six months in the job, Menezes resigned. On 31 May 2008, Manuela Ferreira Leite became the first female leader of a Portuguese major party. She won 38% of the votes, against the 31% of Pedro Passos Coelho and the 30% of Pedro Santana Lopes.
