In 2007 the MRE was a founding member of the Democratic Party (PD), but continued to exist as an associate party and retained almost entirely its autonomy. In the 2008 general election, Sbarbati and Musi were elected to the Senate and often distinguished themselves from Democrats in key votes. Notably, they opposed European Parliament electoral law reform in 2009.[4]
The common battle against electoral reform favored a reconciliation with the PRI. During the 2009 congress of the MRE the two parties signed a joint declaration, under which - despite their different coalition allegiances - they pledged to join forces on key issues, especially those concerning civil liberties and freedom of research.[5][6]
In April 2010, Sbarbati led the MRE out of the PD and joined the Union of the Centre (UdC) in the Senate.[7][8] In January 2011 the party sought a reconciliation with the PRI, which was reached two months later.[9][10][11]
