Just to reinforce the silliness of trying to predict from these data, it is noteworthy that Obama's average approval rating thus far in the summer of 2011 (45.2%) is close to those of Johnson (1967), Ford (1975), Clinton (1995), Reagan, (1983), and Nixon (1971); and this group of elections turned out to be either narrow losses or substantial victories for the incumbent party.
