It's not so much that he's may or may not be a racist. But he sure dose exercise poor judgment.
The people he supports are racist. i.e Wright
The people he calls friends are crooks. i.e. Obama who denied an inappropriate fiscal relationship with Tony Rezco, only to later admit that the notorious and allegedly criminal Chicago hack had directly intervened to help Sen. Obama buy a multi-million house.
The campaign had initially claimed Rezko-connected contributions were no more than $60,000, an amount the campaign donated to charity. Then the figure grew to around $86,000, and there were
additional revelations that put the amount at about $150,000. Obama's [new] $250,000 accounting was a substantial jump and clearly contradicted earlier campaign statements that Rezko was just one of "thousands of donors."
And he's untruthfull about the NAFTA talk.
