Senate bill similar to Chafee bill in 1993

I have written quite a bit about how the Senate bill is reminiscent of the Chafee bill, which featured an individual mandate, and the most comprehensive Republican alternative to the Clinton Plan in 1993. Kaiser Health News with a summary table comparing Senate bill, Chafee bill, and Rep. Boehner's bill that was released in November, 2009. It would be very useful for the summit to focus on whether the Republican party really has changed on this (many have changed within the past year) and is now diametrically opposed to an individual mandate. A real discussion of the pros and cons of such a mandate would be useful for the nation.
