Martha Coakley Concedes!

Saw it first at Jim Geraghty's Twitter. But see also Politico, "Coakley Concedes":

The Boston Globe reports that Martha Coakley has called Scott Brown to concede, according to a Brown aide.

Two Democrats confirmed the concession to POLITICO.

Her concession marks the most dramatic political upset in a generation, one that will be plumbed for meaning and spun over the next few days.

Please let me know what you think it means in the comments section, as I figure out what I think it means.
