Think.
Where did you hear about Ayers? About Wright? Who was pushing those stories? Where were they being heard? The New York Times?
Did you see anything in the mainstream media on these subjects that did NOT fall under the basic category "nothing to see here, move along?" Especially once Hillary was out of the race and Obama was the candidate?
Would you have heard one damn thing about Wright, Ayers, or any of the rest if there had been no alternative media at all?
