(CNN) - In what could be a bad sign for John McCain, more voters than ever before this election cycle feel the economy is the most important issue to their vote - a subject on which Barack Obama has consistently held an advantage.
According to a new CNN/Opinion Research Corporation poll, nearly 6 in 10 registered voters now say the economy is more important than any other issue - a number that is almost a double digit jump from a similar poll taken in July. And it's nearly double the 35 percent of voters who thought the economy was the No. 1 issue in January.
Meanwhile, the issue John McCain is strongest on - Iraq - has steadily declined in importance among voters. In the latest poll only 10 percent of registered voters say it is most important, down from 25 percent who felt it was most important in July.
The poll was conducted September 19-21, entirely after the crisis on Wall Street unfolded. It surveyed 909 registered voters and carries a margin of error of plus or minus 3 percent.
