Remember Jean Marie's election success of 2002 where socialist candidate Lionel Jospin was beaten in the first election round. Marine's 18 % result is worrying, but what is your "darker times" forecast good for? As an incitement to extend your savings at the bank? To look for an opportunity to leave Europe for safer places? If you perceive such nationalisms as a problem, keep working against them like I also try to do. By the way, I already found the atmosphere quite tense under Sarkozy.
