Senate Majority Leader Harry Reid appears poised today to announce his intent to include a public option with an opt out clause in the bill he brings to the Senate floor.
Policy details will likely be scarce, and the draft bill could still change. What goes to CBO will have different options under certain sections of the legislation, and there are conflicting reports that Reid might ask the CBO to send back analyses of other versions of the public option. Though most on the left would prefer it if public option compromises would simply be suffocated of all oxygen, it's also true that if a public option with an opt-out clause is included in the base bill, it will to a great extent shape the the floor debate. (For instance, 60 votes would be required to strip the public option out of the bill.)
Democrats are being very tight lipped today about exactly what Reid will say, but are suggesting strongly that there will be news.
