The Tax Policy study you're citing made assumptions based on the vague statements Romney has made about policy. With the lack of cuts programs, cut taxes for the rich and promise to reduce the deficit he has to raise taxes on the middle/working class to make this happen. Maybe you're right and the middle class tax raises won't happen. But then where is that money coming from? Don't get me wrong, Obama's plan is very vague as well and that's a problem as well, but his plan at least makes some sense. Also keep in mind that sharp austerity to cut the deficit WILL drag the economy. A lot. So if you push that position, keep that in mind.
