Thanks to NAFTA and the trial of Tony Rezko, yesterday wasn't a great press day for Barack Obama. But he at least got a little encouraging news about some meaningless endorsements from P. Diddy and 50 Cent. Russell Simmons said yesterday during his press conference endorsing Obama that Diddy called the Obama campaign and hinted that 50 Cent might defect to Obama because he "didn't know about Hillary anymore." 50 Cent endorsed Clinton last month, citing doubts about America's readiness for a black president and his concerns that Obama might be assassinated if elected.
