Putin's campaign manager. Putin won the election with 52.94% of the popular vote. Medvedev was quoted after the election commenting he thoroughly enjoyed the work and the responsibility calling it "a test of strength". As president, Putin launched a campaign against corrupt oligarchs and economic mismanagement. He appointed Medvedev chairman of gas company Gazprom's board of directors in 2000 with Alexei Miller. Medvedev put an end to the large-scale tax evasion and asset stripping by the previous corrupt management. Medvedev then served as deputy chair from 2001 to 2002, becoming chair for the second time in June 2002, a position which he held until his ascension to presidency in 2008.

In opinion polls which asked Russians to pick their favourite successor to Putin from a list of candidates not containing Putin himself, Medvedev often came out first, beating Ivanov and Zubkov as well as the opposition candidates. In November 2006, Medvedev's trust rating was 17%, more than double than that of Ivanov. Medvedev's popularity was probably
