I'm of the opinion that Wright and his ilk DON'T want Obama to win. I mean, why else say the most incredulous things at a time when Clinton is regaining momentum and that there is a very realistic possibility that a black(well, half black anyways) can ascend to the White House? Sure, there are excerpts of Wright stating things as late as 2003, but very little to nothing before that time. Obama is correct in stating that Wright is not the same man he met 20 years ago.
So, why not? For one, if Obama does not become president of the United States, then Wright, Farrakhan, Jackson, Sharpton, the NAACP, the Urban League, and other so-called civil rights activists can sit back and say "See? Told ya so, the US is racist and will not tolerate having a black president." This way, they can continue with the race hustling, extortion, constant media exposure, and continue to collect tens of millions as their big business produces the phantom Great White Bigot.
Or, more simply, Wright just wants his time in the sun. He knows he will probably be forgotten soon anyways, at least up until Obama loses either the nomination or the presidency, or if he even attains it. Perhaps Wright is simply human like the rest of us, and will say and do anything to garner national attention.
