I say we call 'em, "Socialist democrats," to stress their true nature up front.
Isn't democracy impossible under socialism?
Yes, but you get to vote for your favorite socialists.
When I was in school, I was taught that socialism was a compromise between communism and capitalism, and as such worked better than either individually. There is still a free market concept in socialism, but the government is able to influence the markets in a beneficial way by controlling the large industries.
My point is that exposing the Democrats as socialists doesn't do much when the majority of the people don't really understand why socialism is bad. The promises of socialism all sound great: free health care, help to needy families, free public transportation, punishing the evil rich people.
What is needed is a campaign to explain why capitalism and limited government is the right way to go, and that the Democrats are pushing for total government control of everything.
I have written before on why socialism is doomed to fail, but capitalism has a high probability of success, but I won't repeat that here.
