Nope - the Dems are now bound to putting forth a black (or very dark Hispanic) candidate for the foreseeable future.
And they will...
The irony it is White Liberals (especially White Male Liberals) that are marginalized first.
Blacks & Hispanics are the most racist groups out there. They only vote for their own and they surely are not going to let White Liberals rule them. Look at Philadelphia, Detroit, Los Angeles or any big city. There will never be a White mayor again. In many cases there isn't a single White on the city council or at the head of any Department. Soon we will be saying that about whole states. Once a Democrat seat goes black, it don't go back.
And while Black & Hispanics are Liberals when it comes to getting goodies from YT, they don't care about things that White Liberals care about like Women, gay and Animal Rights (How many blacks are on the Sea Shepard?).
Worse, these single white women better enjoy their free birth control now, because there is no way 20-40 years from now, Blacks & Hispanics are going to be happy paying Social Security for all these Childless White Liberal Females
The bad news for us is that it probably means Moochelle will be running in 2016
