(CNN) – A new poll released Wednesday indicates the presidential race is still locked up between Mitt Romney and President Barack Obama, less than four months before Election Day.
According to a new CBS News/New York Times survey, Romney holds a slight edge over Obama, 47% to 46%. The margin falls well within the sampling error.
However, not everyone has made up their mind. The poll indicates that one in five voters say they could change their decision by November.
Also of note, most voters say Romney’s wealth and history at the private equity firm Bain Capital will make no difference in their vote. Seventy-three percent said his wealth will not be a factor, while 60% said his time at Bain will not make a difference.
The results come after several weeks of intense scrutiny over Romney’s personal financial portfolio, as well as his tenure at the firm. Obama’s campaign and top Democrats have repeatedly called on Romney to release more tax returns than the two years’ worth of tax information he has already made public, pressuring him to answer questions about his offshore accounts.
Romney, however, has vowed not to make public any more tax returns, saying it will simply give Democrats information for them to “distort” and use against him.
"I'm simply not enthusiastic about giving them hundreds or thousands of more pages to pick through, distort, and lie about," he said Tuesday in an interview with National Review Online.
CBS News/New York Times interviewed 1,089 adults over the phone between July 11 and July 16, 942 of whom said they were registered to vote, with a sampling error of plus or minus three percentage points.
