What is so radical about Obama's platform?  Is it the energy policy that emphasizes local/renewable production?  Is it a return to pay-as-you-go fiscal discipline that balances the budget?  Is it the attempt (however flawed) to provide health care to more Americans?  Is it his plan (favored by most Americans) for a phased withdrawal from Iraq?  Is it the attempt to increase grass roots participation in our Democracy, is that a radical far left principle?

What exactly is this 'far left' and why exactly should I be afraid of it.  Please explain.

Thanks.
