Vidalín began his political career in the 1980s, as an
Edil (member of the department's legislature) from 1985 to 1989. In 1990 he was appointed Secretary General of the Intendancy of Durazno by Intendant Raúl Iturria Igarzábal. He served in the post until 1995, when he returned to a seat in the legislature. In the
1999 general election, Vidalín was elected
National Representative for the 45th Legislature, but promptly resigned to run for Intendant in the
2000 municipal elections, in which he was elected. In the
2004 general election he was elected
Senator of the Republic, but again resigned from his seat. In the
2005 municipal elections he was again elected Intendant of Durazno with more than the 50% of the vote. In 2007 he served as an observer in the
election in the Kingdom of Morocco. However, in December 2008 he endorsed
Luis Alberto Lacalle for president. In 2009, faced with the constitutional impossibility of a third term as Intendant of Durazno, Vidalín participated in the
general election, being elected National Representative for the Department of Durazno in the 47th Legislature. In turn, in the third annual period (2012) he served as the fourth vice president of the Chamber. In 2014 he was re-elected to the position of National Representative, but resigned to participate in the
2015 municipal election, in which he was elected Intendant of Durazno with 41.19% of the vote. In 2015 he obtained the Legion of the Book Award from the Uruguayan Book Chamber. In September 2019, he was proclaimed the sole candidate of the
National Party for the Intendant of Durazno in the
2020 municipal election. In the elections, which were postponed until September 27, 2020 due to the
COVID-19 pandemic, Vidalín was reelected in the position for a fourth term with 48.5% of the vote. == Personal life ==
