As Michael Gecan makes clear in his brilliant little book, After America's Midlife Crisis, Obama wasn't much influenced by the ethos or values of community organizing. After all, he spent less time in that role as a low level street worker than in college. The reality is that he was far more a creature of Chicago's Daley Machine politics and the rarified atmosphere of the University of Chicago's constitutional law environs.
The Righteologues trump up Obama's brief stint as a community organizer for their own demonizing purposes. Dragged in to this fiction is the falsification of Saul Alinsky's track record, organizational innovations and legacy.
