Obama’s presidency in video form:

(CNS News) — President Barack Obama not only had his worst overall week in Gallup’s presidential job approval survey last week — with only 40 percent of American adults polled saying they approve of the job he is doing as president — but his approval also tied all-time lows among women and blacks while hitting an unprecedented low among Democrats.

In the demographic breakdown of last week’s Gallup presidential approval polling, which Gallup released today, Obama’s approval tied its record lows of 43 percent among women and 81 percent among blacks.

It hit an unprecedented low of 74 percent among Democrats.

(Obama’s approval was 9 percent last week among Republicans, two percentage points above the all-time low of 7 percent it hit in the week of Oct. 11–17, 2010.)

Before last week, Obama’s approval among women had hit its record-low 43 percent in the weeks of Aug. 1–7, 2011 and April 11–17, 2011.

Also before last week, Obama’s approval among blacks had hit its record-low 81 percent in the week of Feb. 28–March 6, 2011.
