The Nazis were horrible , awful people. But they were political geniuses.

They knew exactly how to target every major group in society to get them on their side. Their anti-communist rhetoric bought them the support of the middle classes, it also somewhat appealed to big businesses and the upper class but they made sure to appeal to them independently as well. Then they appealed to rural populations with their anti-trade unionism as a lot of people in these areas couldn’t afford to pay their workers more like unions demanded. This same policy appealed to workers, too, as he promised to increase workers rights. He prioritised women by promising to make the family more important and protect their roles as mothers and wives. And then the discipline of the SA and the threat of unemployment brought young people on board.

Of course the anti-Jew part is a big part of it. But he revived the stab in the back theory, a belief that Germany was on the verge of winning WW1 when she’d been betrayed by the Weimar Republic and Jews. This appealed to the German people who hated article 231 of the Treaty of Versailles - the war guilt clause. It gave people a scapegoat and a common enemy.

That’s more or less a basic summary, however it’s really clever when you look into it in more detail. He somehow managed to appeal to all of these contrasting groups despite claiming to be for workers and socialists, they did a lot of things even during campaigns before they had any significant power that would conflict their interests amongst the workers.
