A member of
Christian Democracy (DC) since the late 1980s, Valdegamberi joined the
Christian Democratic Centre (CCD) in 1994, after DC's disbanding. He was twice elected mayor of
Badia Calavena. He was first elected to the
Regional Council of Veneto in
2005 for the
Union of Christian and Centre Democrats (UDC) and was regional minister of Local and Social Affairs in
Giancarlo Galan's
third government (2005–2010). Re-elected in
2010, he was appointed floor leader of the re-branded Union of the Centre (UdC). In April 2013 Valdegamberi introduced a bill in order to call a referendum on Veneto's independence by the end of the year. A month later, he left the UdC over disagreements with the party's leadership and formed a Christian-democratic regional party, "Popular Future", along with other two regional councillors (
Raffaele Grazia from the UdC and
Gustavo Franchetto from
Italy of Values). The new party was joined also by
Giampaolo Fogliardi, who had been a deputy of the
Democratic Party until February 2013. In June 2014 the Regional Council passed Valdegamberi's bill, but the referendum was later ruled out by the
Constitutional Court as contrary to the
Constitution. In the
2015 regional election Valdegamberi stood as a candidate in
Luca Zaia's personal list and was re-elected handily in the provincial constituency of
Verona. In the
2020 regional election Valdegamberi, then a full-fledged member of Zaia's
Liga Veneta party, was re-elected from Zaia's personal list from the province of Verona. Valdegamberi is a traditional conservative and has been a founding member of the
pro-life caucus within the Regional Council in July 2023. He routinely presents pro-Russian views and according to an investigative article he may have received funding from Russia's International Agency for Current Policy. As of November 2023, Valdegamberi is no longer a member of Liga Veneta. In April 2026, he joins
National Future led by
Roberto Vannacci. ==Publications==
