I'm unconvinced. The Black Block of the Democratic Party has been kicked around a *LOT* recently, starting with McAuliffe stealing Jackson's (of Atlanta's Democratic Party machine fame) DNC job, Pelosi taking the House Minority Leadership role over Ford, and Donna Brazil being told to go to the back of the Party bus by the lilly-White elites like Shrum who ran Senator Kerry's Presidential campaign into the ground.
I mean, if you are a Black Democrat, you've watched *every* position of power go to some lilly-White racist like Reid. At some point, this much overt pain becomes obvious even to the slowly boiling lobster in the pot.
Are Black Democrats to that point? Probably not...but this letter to Reid is no doubt a sign that Black Democrats are aware that a problem exists.
...And should Black Democrats look further into the matter, they will no doubt ask why White Democratic leaders are *opposing* school choice vouchers/scholarships for inner-city minority children. No doubt they will question why White Democratic leaders are opposed to privatizing Social Security (the only way that Blacks can pass their SS contributions to their heirs, after all, since Black men average living only to age 61, whereas the currently unprivatized SS system only makes SS payments to you starting at age 65).
Black Democrats are *already* asking why White Democratic leaders favor abortion-uber-alle, as most abortions occur in the inner-city, in effect serving as a homegrown self-genocide of an entire race that has now lagged behind Hispanics in total numbers in the U.S.
So this letter from the CBC to Senator Minority Leader Reid may be mere window-dressing as you claim, but I'm unconvinced. In fact, I hold that one alternative to your theory is that the CBC would rather be getting Colin Powell and Condi Rice appointments from a Big Tent rather than continue to be kicked in the teeth by lilly-White liberals who have so far conspired to keep every Black of any note from any major Democratic Party position of power.
