Everyone is trying to figure out why Gov. Deval Patrick appointed William “Mo” Cowan as the interim senator from Massachusetts.[A mentor to many, he made his own way:  For Mo Cowan, a path that began in small town North Carolina leads to the US Senate, by Michael Levinson, The Boston Globe, January 31, 2013] 

Aside from being Patrick’s former chief of staff, everyone is wondering just why Patrick selected this relatively obscure figure to be senator.  Hmmm.
