Although Democratic healthcare proposals may have gotten more attention during the primaries, Republican John McCain's plan might be more revolutionary. McCain wants to tax workers on the value of the insurance they receive from employers, and offer everyone a federal tax credit to help them pay for insurance. The goal, McCain said, is to give those without company-provided health insurance the same tax advantages as those with coverage through work. It would also encourage individuals to shop for less expensive insurance and push prices down, say supporters.
