I would bet the opposite.
Obama really hurt himself with the Trevor Martin remarks.
I feel he lost folk like me, a white old man who voted for him the first time cuz he was Black, hoping to alleviate some of the race stigma.
Holder can take the sting (backlash) out of the investigation if it favors the law enforcement.
No way can they call this guy an Uncle Tom, etc, without looking like a fool (read Jackson, Sharpton, etc).
Given the fact the Governor is a democrat with a Republican lieutenant gov..... I believe the scrutiny won't allow such.
It needs closure, Obama needs closure, the democrats who are up for elections need closure......
I could be wrong, I am good at that
