In the 18 August 2007 Assembly elections, the party won 4.62% of the popular vote and no seats as all of them were won by the ruling Nur Otan party. The JSDP did not recognize the election results, citing numerous violations of the country's electoral legislation.

On 13 October 2009, a joint statement of the JSDP and the Azat was issued on the merger, which, according to the text of the statement, “will mark a new stage in the democratic movement,” and "the united party will become a full-fledged counterbalance to the party of power [Nur Otan]."
