Holland Cotter on Peter Saul (Times sign-in prob. required). One of Cotter's theses is that Saul is the Real Deal while Carroll Dunham and Elizabeth Murray got careers (to put it more bluntly than Cotter does). Check out the slide show: scrumptiously painted early work gives way to psychedelic boils and sores. Compare CO Itchee Bitchee, 1964, with Bush at Abu Ghraib, 2006, for examples of success and failure of politically-themed art.
