WASHINGTON (CNN) - More than half of registered voters say electing Barack Obama is slightly riskier than choosing John McCain, according to a new CNN/Opinion Research Corp. Poll released Wednesday.
In the poll, conducted July 27-29, 57 percent say Obama would be a risky choice, while 54 percent say the same of McCain.
When asked whether Obama would be a “very risky” choice, 31 percent agreed - while only 21 percent said the same of the presumptive Republican presidential nominee.
But when asked which candidate is “somewhat risky,” 33 percent chose McCain; 26 percent said Obama would be.
The poll is based on interviews with 914 registered voters, conducted by telephone on July 27-29. The margin of error for both questions is plus or minus 3 percentage points.
Though slightly more registered voters find Obama a riskier choice, the race continues to remain tight.
A CNN “Poll of Polls” released Tuesday shows just five points separate the two candidates - Obama's 48 percent to McCain's 43 percent, with 9 percent undecided.
While “risk” is not defined by a single issue, one issue in particular may help Obama ease fears over the course of the campaign season.
In a CNN/Opinion Research Corp. poll released Wednesday morning, 48 percent of those surveyed said McCain and Obama’s economic policy would be the most important issue when deciding who to vote for this fall.
But when it comes to deciding who is the better choice to fix the economy, Obama is their pick by a 54-43 percent margin.
That poll had a margin of error of plus or minus 3 percentage points.
The CNN "Poll of Polls" consists of four surveys: CNN/Opinion Research Corporation (July 27-29), AP-IPSOS (July 31-August 4), USA Today/Gallup (July 25-27), and Gallup tracking (August 2-4). The Poll of Polls does not have a sampling error.
