ALD was originally formed as an electoral list, affiliated to The Union, for the 2006 general election comprising: the Democrats of the Left (DS), The Daisy (DL), Valdostan Renewal (RV), Vallée d'Aoste Vive (VdAV), Alé Vallée (AV), the Communist Refoundation Party (PRC), the Federation of the Greens (Alternative Greens) and other minor parties.
The alliance, comprising three party lists (the Democratic Party–PD, RV–VdAV and Rainbow Aosta Valley–AvdA), won a mere 27.4% of the vote, being severely defeated by the UV-led regionalist coalition, which won 62.0% of the vote and confirmed its stable majority in the Regional Council.
[7] In the 2013 general election Patrizia Morelli (ALPE, ALD) was defeated by Albert Lanièce (UV, VdA) 37.0% to 30.8% for the Senate,[8] while Jean Pierre Guichardaz (PD, ALD) came third after Rudi Marguerettaz (SA, VdA) and Laurent Viérin (UVP).
[11] In July 2015 and June 2016 the regional government, formed by the UV and SA, was enlarged to the PD[12] and the UVP,[13] respectively.
[14][15][16][17] In October Marquis resigned and was replaced by L. Viérin (UVP) at the head of a coalition composed of the UV, the UVP, the PD and the Valdostan Autonomist Popular Edelweiss (EPAV),[18] the latter formed by a pro-UV group of splinters from SA who had not endorsed Marquis' government in the first place.
