What is the difference between a modern day Democrat and a Socialist?

[MLR]

Definition of Socialism:
http://www.merriam-webster.com/dictionary/socialism
"Since Democrats do not advocate the government controlling the means of production or the abolition of private property, I'd say it should be clear to anyone with at least a double-digit IQ that Democrats are not Socialists in any way."
I don't care what Democrats say they advocate, but I do watch what they do.
"Do they really believe that the Democrats advocate nationalizing large sectors of the economy?"
No only a true moron would come out and say they advocate it, but then there is Healthcare.
