I think it's a general liberal philosophy. They put their faith in government and if it sounds good to them they support it.

Universal health care sounds well meaning so they don't dig much beyond that. If you speak out against it with a few facts then you are deemed an angry selfish person.

Add to to the fact that many liberals really do believe that from each according to his ability, to each according to his need and you have a recipe for disaster which is what we have going on now.
