Simple reason: they have overcome! Here's Charles Krauthhammer:
Dr. King's dream began to be realized when President Lyndon
Johnson passed the Civil Rights Act of 1964. ... It took a president to get it
done. -- Hillary Clinton, Jan. 7
The analogy Clinton was implying was obvious: I'm Lyndon
Johnson, unlovely doer; he's Martin Luther King, charismatic dreamer. Vote for
me if you want results.
Forty years ago, that arrangement -- white president
enacting African-American dreams -- was necessary because discrimination denied
blacks their own autonomous political options. Today, that arrangement -- white
liberals acting as tribune for blacks in return for their political loyalty --
is a demeaning anachronism. That's what the fury at Hillary was all about,
although no one was willing to say so explicitly.
I'm thinking that the Dems have taken the black vote for granted too long, keeping them satisfied with government tribute, while quietly but steadily blacks have been increasing their gains into American society ON THEIR OWN. You can't go anywhere without seeing them in all positions of government and industry. This is the American Dream fulfilled, and they are saying to the liberal panderers and opportunists like the Jacksons and Sharptons, who want to keep them victimized and servile WE DON'T NEED YOU ANYMORE, if they ever did.
