WSJ if memory serves, take it up with them. The economy being #1 came from multiple sources however.
It depends on how you ask the question - if the source listed “health care” as a generic issue with all others, it was one result - or if “jobs” and “the economy” were two separate issues - it was another - but when Obama Care, or even the Affordable Care Act - was in the survey specifically, it was different still.
Which shows the obscenity of these polls sometimes - jobs, the economy, Obama Care, are ALL RELATED. Obama Care is one reason people are upset about the economy and jobs!
