That's a good question, and we did try to test that crudely. We asked the question up front without providing any information. Throughout the survey we would inform the people that there would be profound costs in the billions of dollars, and that these would be shouldered by taxpayers. We found that there was only a modest decline in the most-enthusiastic-support category. People who shifted made up 15% of the sample. This is out of the 65% who at the outset said that they strongly supported it. There were only 9% opposed, and only 2% were strongly opposed. That dropped down by about 12 points. We didn't find that there was any increase in opposition. Of course, people would always prefer it to be free, definitely.
