I doubt this will have any effect on Obama's political future. People (well liberal people, anyway) love the guy and will rationalize whatever implication there may be. Besides, it seems like a clean deal from what we've been told, just a deal with a bad actor.
I sure hope you are right about Rezko sinking the latest crooked governor of IL however!
The REAL question you should be asking, is how many of Obama's books did he buy???
I saw his book in the Dollar Bin, 3 weeks after it came out. I wwondered THEN why It was doing so "Well"...
