After 1990, Rebengiuc remained a critic of the Salvation Front's successor, the Social Democratic Party. He felt that "The party in power immediately after the Revolution only changed its name and high-ranking leadership, that is all. People were still tied to the communist party's mentality." During the early 1990s, Rebengiuc sympathized with the opposition National Liberals, and, without formalizing his affiliation, ran in elections for the Senate in the 1990 suffrage. Rebengiuc later reflected: "Fortunately, I was not elected." The actor also publicized his monarchism: in April 1992, he was one of the celebrities welcoming Michael I, the deposed King of Romania, during his return visit to the post-communist country. In 2003-2004, Rebengiuc was affiliated with the minor party Union for Romanian Reconstruction (URR). He later stated: "It was a political proposal I believed in. URR could have been a change of the political class." He indicated that his reasons for parting with the group was its failure to gain popularity and reach the number of votes necessary to enter Parliament during the 2004 elections.
