Perhaps worth placing Marine Le Pen’s far-right National Rally (RN) on the deplorables list. They have been advancing in France so much that "Macron’s centrist list, headed by MEP Valérie Hayer, scored between 14.8% and 15.2% in the European poll, less than half the 32%-33% tally booked by RN, whose lead candidate was the party’s president, Jordan Bardella, 28."
I think there's a reason for this: centrist leaders have not done anything to better people's lives. They have not improved the economy, jobs, housing, health and, least of all, education.
Poor, uneducated people vote for "strong" leaders.
