Has the Catholic Church ever excommunicated someone based on their ideology?

I know the Catholic Church excommunicates Catholics who join Freemasonic lodges, as well as Catholics who the Church judges to be willful heretics. But has the Church ever excommunicated a Catholic purely for being a member of a Communist or National Socialist party? The Church has never excommunicated Adolf Hitler, and some other Catholics who belong to Marxists groups, so I'm curious.
