There's an ominous trend for President Obama in the latest Allstate/National Journal Heartland Monitor poll: not only is his overall approval rating lagging, but he's lost as much (or even more) ground among groups that favored him in 2008 as among those who resisted him last time.
The chart at left compares Obama's vote among key groups in 2008, according to exit polls, and his job approval rating among them in the latest Heartland Monitor released Thursday morning. (The survey, conducted by FTI Strategic Communications, polled 1200 adults by landline telephone and cell phone from November 30 to December 4 and has a margin of error of plus or minus 2.8 percentage points.)
Overall, Obama has slipped from 52.8 percent of the vote in 2008 to 44 percent approval in the new survey with 49 percent disapproving. As the chart shows, Obama has declined not only in the groups that were always dubious of him, but also with several that enthusiastically joined his winning 2008 majority.
