On 29 May 2008, the ADR deputies and Jaerling were the only members not to vote for the Treaty of Lisbon. In the 2009 Chamber election, the ADR held on to four seats (of which, 2 in Sud), but with a reduced vote share of 8.1%: its worst legislative election result since its first election, in 1989, whilst its vote share fell - albeit by less - in the simultaneous European Parliament election, to 7.4%. Jaerling, running for his own Citizens' List, failed to win a seat in either. This had been in spite of strong pre-election polling, the difference likely to be attributable to the financial crisis pushing voters to more familiar parties.
