it would be nice for those supporting single payer to first describe exactly how the funding would work. Instead of trying to hide it under a mismash of taxes, like Obamacare, just come out and say (for example), there will be a X% tax added to FICA, where the employee will pay 1/2 and employer pay 1/2. Or a VAT tax. Or whatever. Just come out and say what it will cost instead and how it will be funded. Instead its always about the benefits while avoiding any mention of new tax.
just be honest about it.
