This was all over the place last week, but I just realized I didn't post it here. Since there's been some confusion about the public option, I thought it might be good a idea to turn to Mr. Reich for some simple answers.
The only thing he didn't cover was specifically who can buy into the public option as soon as it goes into effect. That can be learned using this handy chart.
Adding... I almost forgot to include a link to my own explanation.
