Since the 1980s has been an important political party winning local, state, and national elections. In 2000, PAN candidate Vicente Fox was elected for a six-year Presidential term; in 2006, PAN candidate Felipe Calderón succeeded Fox in presidency.

In the 2012 Legislative Elections, the PAN won 38 seats in the Senate, and 114 seats in the Chamber of Deputies.
