Boc was also the president of the Democratic Liberal Party (PDL), which proposed and supported him as Prime Minister in late 2008, from December 2004 until July 2012.

[1] Before the Romanian Revolution of 1989, Boc was, together with future PSD leader Ioan Rus, president of the Association of Communist Students [ro] of Cluj County.

[2] Boc's entrance into mainstream Romanian politics was in 2003, when he was elected executive president of the Democratic Party (PD); he had been proposed by Traian Băsescu.

In that election, Funar lost out in the first round to both Boc and the Social Democratic Party (PSD) candidate Ioan Rus.

Eventually, Boc was reinstated as prime minister after the presidential elections ended with the victory of incumbent president Traian Băsescu who supported him.
