National Journal's Major Garrett (Major is his name, not his title) has an outline of what the compromise debt ceiling deal could look like. I believe he has good sources, and is likely to be accurate.
Garrett says the deal will look much like the tentative deal negotiated a week ago by Senate Majority Leader Reid (D-NV) and House Speaker Boehner (R-OH). That deal the president then rejected but is now likely to accept.
