The Democratic Party (PD) started to lose support by the late 2000s in the Po Valley. The first election in which the Democratic Party lost to a more radical party was the 2010 Venetian regional election (20.34% of the vote, compared to the 35.16% obtained by Lega Nord). The party's 18.8% vote share in the 2018 Italian general election meant it lost 185 seats in the Chamber of Deputies and 58 seats in the Senate, falling from the largest to the third-largest faction in the Italian parliament. This was particularly dramatic considering that the party received more than 40% of vote just four year prior, in the 2014 European Parliament election in Italy, and is commonly attributed to its enforcement of austerity measures, a poor economic recovery and a failed attempt to move towards a two-party system in the 2016 Italian constitutional referendum. However, the party still came in second place in the popular vote and entered government in September 2019 with the Five Star Movement after the collapse of the previous Conte I Cabinet.
