Poll Tracker

Even though 35 percent of Americans believe a terrorist attack somewhere in the United States is likely over the next several weeks, that is the smallest percentage measured in the seven years since Sept. 11, according to a CNN/Opinion Research Corp. survey released Wednesday.

The pollsters note that from 2002-2006, a majority of those surveyed feared an attack in the "next several weeks."

CNN's polling director, Keating Holland, notes that this drop could have a political impact: "As the threat of a terrorist attack continues to recede in the mind of the American voter, the state of the economy and other domestic issues are likely to become even more important. That would be good news for Sen. Obama, since the Democrats currently beat or tie the Republicans on every issue except terrorism."

The telephone survey was conducted Thursday through Sunday and has a margin of error of +/- 3.5 percentage points
