Well the scary argument they constantly dredge up is how bad health care is in the countries that provide single payer. Just read this and be sure afterward you spread the word as if the righties win in November, even the care many people have will deteriorate if they are among the working poor unable to afford the best and not eligible for Medicare or Medicaid.
My belief is we need to be working hard for single payer in the U.S. Enough already with buying what the corporate interests use for scare tactics. Universal health care will not deteriorate everybody's care.
