I think that's too optimistic. For example, I suspect that not one American in ten understands and embraces the constitutional doctrine of enumerated powers.
My (implied) point was that many of these 44% have some favorite part of the Constitution (e.g. free speech, which was highlighted in the poll) that they think has been transgressed by Congress.
For example, I'll bet we can find a lot of conservatives who rightly think that McCain-Feingold is unconstitutional on First Amendment grounds, but they don't understand that this law is an unconstitutional atrocity in many other ways as well.
I can’t argue with any of that, at least the 44% do realize that the government is overstepping the boundaries, it is astonishing to think that more than half the people either don’t think so or are not certain. How can anyone who knows anything NOT KNOW that the government is living outside the constitution?
Just this morning after answering your post I had a conversation with a seventy year old man who seems to think there is a lot of positive to the idea that a person charged with a crime should be considered guilty and have to prove his own innocence. I was astounded to say the least, a large percentage of America seems to be looking forward to dictatorship as if it meant deliverance.
