What is one way that the election of 2000 advanced democracy in mexico?

Kinda of thinking it would be Denied PRI (Partido Revolucionario Institucional) Control of congress and paved way for multiparty democratic rule

The 2000 Mexican General Elections were held in July 2000, with the purpose of electing the successor President of the Republic of Ernesto Zedillo, the 628 members of the Union Congress, and 16 state governments. The presidential election took place on July 2, followed by the legislative election on July 6.

The winner of the presidential election was Vicente Fox of the National Action Party, this being the first defeat of the Institutional Revolutionary Party (PRI) since the Mexican Revolution in 1910. In the legislative dispute, the PAN won 224 of the 500 seats in the Chamber of Deputies, while the PRI won 60 of the 128 Senate seats.
