Some are saying that Senator Obama cannot be held responsible for what his pastor, Jeremiah Wright, said. In their version of events, Barack Obama just happened to be in the wrong place at the wrong time -- and a bunch of mean-spirited people are trying to make something out of it.

Barack Obama's own account of his life shows that he consciously sought out people on the far left fringe. In college, "I chose my friends carefully," he said in his first book, "Dreams From My Father."

These friends included "Marxist professors and structural feminists and punk rock performance poets" -- in Obama's own words -- as well as the "more politically active black students." He later visited a former member of the terrorist Weatherman underground, who endorsed him when he ran for state senator.
