Immediately following the surprise victory of left party coalition New Popular Front in France’s parliamentary elections last week, Jean-Luc Mélenchon — the leftist leader of the bloc’s largest party, France Unbowed — vowed to see France “recognize the Palestinian state as soon as possible.”

France’s far-right National Rally party, alongside conservative centrists, had spent weeks painting the left’s support of Palestine as an electoral poisoned pill. In attacks all too familiar in the U.S., they conflated anti-Zionism with antisemitism, slamming Israel’s critics as antisemites. Israeli officials explicitly backed the far-right party. In this last election, at least, it didn’t work to prevent left-wing success.

Supporting Palestine Helped the Left Win in France and Britain. Will Democrats Learn From It?
