Le Pen focuses on issues related to immigration to France, the European Union, traditional culture and values, law and order, and France's high rate of unemployment. His progression in the 1980s is known as the "lepénisation of spirits" due to its noticeable effect on mainstream political opinion. His controversial speeches and his integration into public life have made him a figure who polarizes opinion, considered as the "Devil of the Republic" among his opponents or as the "last samurai in politics" among his supporters.
