If you're aware of the history of the 1989 Revolution and the Fall of Communism, you'll notice one interesting thing. Several communists, including high-ranking officials, dropped their adherence to communism and reinvented themselves as democratic socialists or social democrats. So if you think that cannot happen the other way around in the West, you'd be wrong. These people are teetering on the edge of being commies, and they'll be well happy to fall in line if a communist party takes power.
