CNN finally adjusted the delegate counts to reflect Edwards being out of the race. He loses a bunch of delegates, but not all of them. Superdelegates obviously are free agents so now are uncommitted again. What happens to the other delegates varies by state. In many cases, the primaries and caucuses are just the first stage in the process, and if the process isn't finished yet, then we end up with uncommitted delegates or delegates to other candidates eventually. In cases where the process is done, in most cases Edwards keeps his delegates. Of course, even then, the delegates are actual people and they may or may not end up voting for Edwards at the convention. This could be affected of course by if Edwards ever endorses. This is also affected by the fact that officially Edwards just "suspended" his campaign rather than ending it. If that status changes, the status of even more delegates changes.
In the mean time, despite all the talk about Edwards leaving potentially helping one candidate or the other, in the short term delegate race in percentage terms it helps Clinton more, as it widens the gap with Obama. Of course, in number of delegate terms, it stays the same. But I'd give the advantage to Hillary here. As a percent of delegates allocated, she is now almost as high as she has ever been.
Oh yeah, and on the Republican side, Guiliani's two delegates go away. But since he had only 2... Ron Paul has three times that amount... it is just barely even noticeable on the charts.
