Have you failed to notice that liberals have great disdain for capitalism. Look at their constant berating of big business and the wealthy. I did a test amongst a few liberal friends, and the word "capitalism" elicits negative responses in and of itself.
Their socialist programs are only stepping stones to full on communism.
Please don't assume I am a liberal, or that I am particulaly sympathetic to liberal causes, I am not.
I just feel the modern Democratic Party, of which I have little use, is a far cry from Communism.
