It would be nice if you could rate each of the positions on a scale of 1 to 5. The way the questions are set, you either agree or disagree, period. But on several of the questions, I had one that was "the best" answer in my book, but several I could live with, and others I don't want at all.
One of the best examples was the question on taxes. I might want to scrap it entirely, but think the flat tax or making the Bush tax cut perminant would be good ideas too, but absolutely oppose raising taxes. The only candidate that will get any "credit" for that tax position is the one that matches exactly, and it rates candidates who want a flat tax, maintaining tax cuts and raising taxes are all the same.
