The Washington Post has this great comparison of the tax plans of McCain and Obama. Basically, both offer tax cuts for most people (sorry, Republicans call them "folks"). But Obama cuts taxes more for people in the middle and bottom of the income distribution. Obama will raise taxes IF and ONLY IF you make more than $600,000/year. And if you do make that much the difference in your tax bill will be around $115,000. So I can certainly see what the super rich would want to stop Obama. But why anyone who can even remotely call themselves "middle class" would be upset about Obama's tax plan is beyond me.
