A new Miami Herald poll finds Sen. John McCain "is nursing a narrow lead" over Sen. Barack Obama in Florida, 47% to 45%.
Key finding: "The survey of 800 likely voters echoed the economic jitters of the nation, as 43 percent of voters said the economy should be the next president's top concern. That's a three-to-one margin over the next two top issues: managing the war in Iraq, at 14 percent, and protecting us from terrorism, at 12 percent."
Said pollster Tom Eldon: "Obama is in a position to improve his poll numbers, given the confidence in his handling of the economy."
