He is considered to be the one who proposed abandoning traditional right-wing party liberal rhetoric and populist slogans such as raising pensions and supporting the poor. Because of the defeat of the Union of Right Forces in the 2007 Russian legislative election and the abolition of single-mandate electoral districts, Anton Bakov did not get into the State Duma for the next term.
