There was a flurry about it in August: WSJ: Dems could split bill, Use Reconciliation
The idea, as I'm sure y'all recall, is to pull out the funding, subsidies they are funding, and then the specification of what the subsidies are for in terms of the exchanges and public option, and pass it under budget reconciliation rules, and pass the balance of insurance regulation reform under regular rules.
With Stupak, this becomes even more urgent, since this language would be on the budget reconciliation side, so it would have a 50 vote threshold to pass.
Its not pretty, and it means we have to mobilize to entrench the new system - but as severely mangled as the House Bill is, a Senate bill that has a 60 vote threshold is likely to be even worse. So Split the Bill.
