This post gets a bit geeky, but hopefully makes a worthwhile point.
In an effort to prop up his his crazy tax proposals without having to explain the details, Mitt now is pointing to "studies" that supposedly support his claim that he won't have to raise taxes on the middle class. You can read the details here:

Inferentially, it seems ole Mitt is relying on the age old conservative theory that reducing tax rates actually causes revenue to increase. The idea is that everyone is so deleriously happy with their reduced tax rates that they work harder and longer, such that the increase in the size of the economy more than offsets the reduced rates. It goes back to a concept coined by Arthur Laffer, known as the "Laffer Curve," which was the theoretical underpinning for the 1981 Reagan tax cuts.
