Poll: Obama's approval rating declines over the summer -- again

Obama’s higher January-April averages are aided by more positive ratings during the honeymoon period of his presidency in early 2009. And his higher average May ratings are influenced by surges in approval in May 2011 after Osama bin Laden’s capture. However, there is no single reading in any June, July, or August during the last five years that significantly lowers the average approval rating for Obama in those months. Rather, his summer ratings are mostly characterized by consistent decline.

His job approval rating has yet to increase from the prior month in any of the 15 Junes, Julys, or Augusts during his presidency — showing a decline in 13 of those 15 months, and no change in the other two.
