In the Chamber, he sat on the Arts, Culture and Mass Media Committee. As minister, his top priority was the preservation of Romania's historic monuments. His ministerial term ended when he was not reappointed to a new cabinet under Boc at the end of 2009. At the
2012 local election, he ran for mayor of Bucharest's
Sector 1, finishing second with 14.1% of the vote. Running in
the legislative election later that year, he placed second in his district, but won another term through the redistribution mechanism specified by the electoral law. In February 2014, he followed
Elena Udrea in resigning from the PD-L and joining the
People's Movement Party (PMP). A year later, he entered the
National Liberal Party (PNL), proclaiming that the PMP had degenerated into a "total fiasco". In June 2016, the PNL expelled him after he criticized the party leadership for its disrespect toward
Save Bucharest Union leader
Nicușor Dan. Paleologu ran as an
independent in the
December election and won some 8,000 votes, well short of the approximately 25,000 needed to secure a seat. By July 2019, Paleologu was a front-runner for the PMP nomination for the
November presidential election. The following month,
Mihail Neamțu withdrew from the party's internal race, endorsing Paleologu. He thus became the party’s candidate, placing fifth with 5.7% of the vote.
