A superdelegate map, and Michigan math

The indispensable DemConWatch has a cool map of where each candidate is getting superdelegate support from. With a few notable exceptions, it's fairly similar to the primary map.

Meanwhile, The Jed Report argues that Edwards's endorsement of Obama "shatters Clinton's Michigan and Florida dreams," because "now that Edwards has endorsed Obama, there's really no fair argument to deny Obama" the 55 "Uncommitted" delegates from Michigan. Jed then does the math, and concludes that, even if Michigan and Florida are seated with full voting rights (but with Obama getting all 55 Uncommitteds), Obama only needs 22% of the remaining undeclared supers to clinch the nomination (this is using the Clintons' preferred "magic number" of 2,210).
