The results for the first round of the French presidential election, 2022, overall:
The results for French living abroad:
The high score for Macron and the low score for Le Pen I can understand, considering what I think I know about the demographics of French living abroad. In cities like New York, London, and Frankfurt, the score for Macron exceeds 50% or even 60% in the first round, with the French living there probably mostly being well off, liberal, and international thinking, perhaps they're even bankers like Macron was. Conversely, the score for the right-wing populist Le Pen is very low.
What I don't understand is the relatively high score for Zemmour, who scores higher with French living abroad than with French overall. In France, Zemmour has less than 1/3rd of the votes that Le Pen has; abroad, he has more votes. Some strongholds are Miami (25% vs. Le Pen 7%), Bangkok (32% vs. Le Pen 11%), Haifa (41%), Tel Aviv (55%). Apparently, one of his talking points was/is against Islam or declaring it non-French ("immigrants should choose between Islam and France"), which may resonate with some Jewish French nationals in Israel, but the pattern is true also in the USA or East Asia. Even though his share of the vote is quite small in cities like London (5.2%) or Berlin (2.4%), it's still nearly double that of Le Pen in the same places.
In France, the only department where Zemmour outscores Le Pen is Paris, with 8.16% for Zemmour and 5.54% for Le Pen. Is it that Zemmour does better in cities and Le Pen better in rural areas, and does that explain both the Paris and the foreign result (probably most French living abroad live in or near cities)? But in Bordeaux, Toulouse, Lyon, Grenoble, or Strasbourg, Le Pen still outscores Zemmour, so that's not the full story. What is it about the political programme and/or the demographics of the voters of Le Pen and Zemmour that explains that Zemmour scores better in Paris and abroad, but Le Pen scores (much) better everywhere else?
