Lots of detail in this Washington Post article about moving the Expos. I especially love this exchange, which tells you how far apart the sides are:

Deputy Mayor Eric Price held up a chart of MLB's last 11 stadium mega-deals, and suggested to the committee that the proper mix had settled at about two-thirds public funding to one-third private -- a deal that would cost the District more than $250 million but also would cost MLB more than $100 million.

The reply came with a smile from the committee chairman, Chicago White Sox owner Jerry Reinsdorf, but it was not taken as a joke.

"Two-thirds/one-third is fine," Reinsdorf said, according to two people present. "But three thirds/no thirds is more of what we had in mind."
