Probably because 1/3 of Americans are actually economically literate. They understand the overwhelming trade and current account deficits. They realize that the massive amounts of credit creation by the Fed (to boost the housing market) is doing great damage to America's international competitiveness.
You are far to generous in your assessment of how many Americans are actually economically literate. I would put the number much closer to 10% I have for many years subscribed to the "90-10 rule". It means that 10% of the people are aware and 90% haven't the first clue what is going on around them either locally or in the world generally.
This is a good reason. It could also be that 1/3 of Americans are now operating at a lower standard of living since they have had to trade thier technical job for something closer to the "bottom rung".

Hopefully, they also understand the fact that our antiquated and horribly inefficient tax system is a major contributor to both of those problems.
