Once again features Thomas Sowell who says:
Once the election is over, the glittering generalities of rhetoric and style will mean nothing. Everything will depend on performance in facing huge challenges, domestic and foreign. Performance is where Barack Obama has nothing to show for his political career, either in Illinois or in Washington.
Sowell then goes on to detail the challenges, but if you have no need to know the specifics, his conclusion will do:
None of this can be prevented by glib talk, but only by character, courage and decisive actions— none of which Barack Obama has ever demonstrated.
