Alsace is one of the most conservative régions of France. It is one of just two régions in metropolitan France where the conservative right won the 2004 région elections and thus controls the Alsace Regional Council. Conservative leader Nicolas Sarkozy got his best score in Alsace (over 65%) in the second round of the French presidential elections of 2007. The president of the Regional Council is Philippe Richert, a member of the Union for a Popular Movement, elected in the 2010 regional election. The frequently changing status of the région throughout history has left its mark on modern day politics in terms of a particular interest in national identity issues. Alsace is also one of the most pro-EU regions of France. It was one of the few French regions that voted 'yes' to the European Constitution in 2005.
