Where does that money come from? Who are the winners and losers?
FactCheck.org breaks it down:
Who saves money and who loses under the plan, depends on the tax bracket an individual or family is in and what their health coverage costs. Lower-income individuals could do better if they have health care through their employer. They'd pay a lower tax rate on those benefits than higher income workers. Those who would benefit most from McCain's tax credit are those who already buy their own private plans and don't receive tax benefits. Those who are uninsured may find the tax credit provides enough financial incentive to sign up for health care policies.
