[1] A resident of Belmopan, Saldivar was the UDP standard bearer for Cayo South in the 1998 and 2003 elections, but was defeated both times by Agripino Cawich of the People's United Party.

[6] Saldivar served as the Minister of Public Service and Government Improvement from 2008 to 2012 in Belize.

Saldivar stood as a candidate for UDP party leader in a convention on 9 February 2020 to replace the longtime incumbent, Prime Minister Dean Barrow, who retired from party politics.

He defeated Deputy Prime Minister Patrick Faber, but three days later was forced to resign after allegations surfaced he accepted US$50,000 from accused fraudster Lev Dermen, who was on trial in Salt Lake City, leaving the future of UDP leadership unclear.

Although he remains a UDP member and in the Belize House, Saldivar was also stripped of his Cabinet post.
