The CNN poll found that the president's ratings fell the most among those living in suburban areas.
"The drop in Obama's approval rating comes entirely among suburbanites," said CNN Polling Director Keating Holland. "Compared to the October CNN poll, positive views of Obama held steady among people who live in big cities and rural areas. But in the suburbs, his approval rating was 45% a month ago but has dropped to just 37% now."
The CNN poll surveyed 843 adults Nov. 18-20 via telephone with a margin of error plus or minus 3.5 percentage points.
