Le Pen and Macron had their last debate before the election on Sunday, Some highlights of the debate are provided in this article. It was a lot like many of the US debates. Lots of shouting at each other and very little substantive debate on the issues. Le Pen's strategy was to personally attack Macron and claim that she was the only one who could protect France from Islamic terrorism. Some how she would defend French borders but she did not provide a plan for achieving her objectives.
Macron presented himself as the sensible candidate and ridiculed most of her positions. It was telling that he criticized her for being too much like Donald Trump. I guess, Trump is a bad word in France.
