House negro... *LINK*
This ex-black panther tells it like it is. Back in the slave days there would be some slaves that would work their way into the good graces of the Masa. As a result, the Masa would allow these slave access to the house, hence...House Negro(and I'm being polite compared to what the field slaves called them). The House negro would side with the Masa and turn on the field slaves to remain in the Masa's good graces so as to "earn" an easy/easier ride.
This ex-black panther is essentially calling Senator Lewis a house negro. He claims Lewis, after being beat down by democrats, has suffered what we now call the Stockholm syndrome and has, since his beat down, been doing the bidding of the oppressors he originally protested.
I think the ex-Black Panther has it spot on.
